In 2019,Beilstein Journal of Nanotechnology included an article by Jana, Achintya; Mishra, Puneet; Das, Neeladri. SDS of cas: 15854-87-2. The article was titled 《Polymorphic self-assembly of pyrazine-based tectons at the solution-solid interface》. The information in the text is summarized as follows:

The synthesis and surface self-assembly of a new pyrazine-derived mol. with pyridine pendants I was reported. Ambient scanning tunneling microscopy investigation at the solution-solid interface revealed polymorphic self-assembly of these mols. on a HOPG substrate. Two different mol. packing structures with equal distribution were observed Detailed anal. of the STM images emphasized the crucial role of weak intermol. hydrogen bonding, and mol.-substrate interactions in the formation of the observed polymorphs. Such weak hydrogen bonding interactions were highly desirable for the formation of modular supramol. architectures since they could provide sufficiently robust mol. structures and also facilitate error correction. The experimental process involved the reaction of 4-Iodopyridine(cas: 15854-87-2SDS of cas: 15854-87-2)

4-Iodopyridine(cas: 15854-87-2) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.SDS of cas: 15854-87-2

Developing mol. circuits that can function as the active components in elec. devices is an ongoing challenge in mol. electronics. It demands mech. stability of the single-mol. circuit while simultaneously being responsive to external stimuli mimicking the operation of conventional electronic components. Here, we report single-mol. circuits based on spiropyran derivatives that respond elec. to chem. and mech. stimuli. The merocyanine that results from the protonation/ring-opening of the spiropyran form showed single-mol. diode characteristics, with an average current rectification ratio of 5 at ±1 V, favoring the orientation where the pos. charged end of the mol. is attached to the neg. terminal of the circuit. Mech. pulling of a single spiropyran mol. drives a switch to a more conducting merocyanine state. The mech. switching is enabled by the strong Au-C covalent bonding between the mol. and the electrodes, which allows the tensile force delivered by the STM piezo to break the mol. at its spiropyran C-O bond. In addition to this study using 4-Iodopyridine, there are many other studies that have used 4-Iodopyridine(cas: 15854-87-2Electric Literature of C5H4IN) was used in this study.

Computed Properties of C5H4IN And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

Here we report two highly emissive perylene diimide (PDI)-based metallacages and explore their complexation with polycyclic aromatic hydrocarbons, such as pyrene, triphenylene, and perylene. The fluorescence quantum yields of metallacages exceed 90% and their binding constants with perylene can reach as high as 2.41 x 104 M-1 in acetonitrile. These features enable further tuning of the emission of the host-guest complexes to obtain white-light emission based on the complementary orange emission of the metallacages and the blue emission of perylene. Moreover, owing to the huge differences of their quantum yields in solution and in the solid state, the host-guest complexes are successfully employed for information encryption. This study offers a general approach for the construction of emissive metallacages and explores their application for information encryption. In the part of experimental materials, we found many familiar compounds, such as 4-Iodopyridine(cas: 15854-87-2Computed Properties of C5H4IN)

4-Iodopyridine(cas: 15854-87-2) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Computed Properties of C5H4IN

《Low-Dimensional Hybrid Indium/Antimony Halide Perovskites: Supramolecular Assembly and Electronic Properties》 was written by Nicholas, Aaron D.; Halli, Ryan N.; Garman, Leah C.; Cahill, Christopher L.. HPLC of Formula: 15854-87-2 And the article was included in Journal of Physical Chemistry C in 2020. The article conveys some information:

The phenomenon of quantum confinement in hybrid low-dimensional lead-free perovskite derivatives continues to hinder the development of these materials for electron carrier devices such as next-generation solar cells. Spatial separation of metal-halide octahedra within crystal structures yields materials with greater moisture and photodegradation resistance, but at the expense of desired photophys. properties such as small band gaps. We report the synthesis and characterization of an unexplored isomorphic series of perovskite derivatives consisting of isolated dimeric metal-halide M2X104- (M = In, Sb; X = Cl, Br) anions charge-balanced with halopyridinium cations. Assembly of these species results in a supramol. network via extensive noncovalent interactions and may be described as a pseudo-zero-dimensional arrangement. Despite the low dimensionality, these materials display semiconductive optical band-gap energies owing to the appearance of an intermediate band due to hybridization of metal-halide at. and MOs. Low-temperature luminescence measurements provide evidence of electron delocalization where photoexcited metal/halide electrons are captured by organic cations via energetically accessible π* MOs, separating electron/hole pairs. Natural bonding orbital (NBO) calculations reveal that metal hybridization is more pronounced in compounds containing Sb3+ and can be influenced by noncovalent interactions between anionic and cationic building units.4-Iodopyridine(cas: 15854-87-2HPLC of Formula: 15854-87-2) was used in this study.

Martin, M. Trinidad; Marin, Mario; Maya, Celia; Prieto, Auxiliadora; Nicasio, M. Carmen published their research in Chemistry – A European Journal in 2021. The article was titled 《Ni(II) Precatalysts Enable Thioetherification of (Hetero)Aryl Halides and Tosylates and Tandem C-S/C-N Couplings》.Category: iodides-buliding-blocks The article contains the following contents:

Ni-catalyzed C-S cross-coupling reactions have received less attention compared with other C-heteroatom couplings. Most reported examples comprise the thioetherification of most reactive aryl iodides with aromatic thiols. The use of C-O electrophiles in this context is almost uncharted. Here, the authors describe that preformed Ni(II) precatalysts of the type NiCl(allyl)(PMe2Ar’) (Ar’=terphenyl group) efficiently couple a wide range of (hetero)aryl halides, including challenging aryl chlorides, with a variety of aromatic and aliphatic thiols. Aryl and alkenyl tosylates are also well tolerated, demonstrating, for the first time, to be competent electrophilic partners in Ni-catalyzed C-S bond formation. The chemoselective functionalization of the C-I bond in the presence of a C-Cl bond allows for designing site-selective tandem C-S/C-N couplings. The formation of the two C-heteroatom bonds takes place in a single operation and represents a rare example of dual electrophile/nucleophile chemoselective process.4-Iodopyridine(cas: 15854-87-2Category: iodides-buliding-blocks) was used in this study.

A one-pot 1,3,4-oxadiazole synthesis-arylation strategy for accessing 2,5-disubstituted 1,3,4-oxadiazoles I [R1 = 3-pyridyl, 4-MeC6H4, 1-phenylcyclopropyl, etc.; R2 = Ph, 4-pyridyl, morpholino, etc.], from carboxylic acids, N-isocyaniminotriphenylphosphorane (NIITP) and aryl iodides, was reported. The reaction sequence, featuring a second stage copper-catalyzed 1,3,4-oxadiazole arylation, was found to tolerate (hetero)aryl, alkyl, and alkenyl carboxylic acids, and (hetero)aryl iodide coupling partners. The effectiveness of the two-stage strategy was exemplified by the late-stage functionalization of five carboxylic acid-containing APIs, and, an extension to the synthesis of aminated 1,3,4-oxadiazoles using N-benzoyloxy amine coupling partners, was also demonstrated.

Huber-Gedert, Marina; Nowakowski, Michal; Kertmen, Ahmet; Burkhardt, Lukas; Lindner, Natalia; Schoch, Roland; Herbst-Irmer, Regine; Neuba, Adam; Schmitz, Lennart; Choi, Tae-Kyu; Kubicki, Jacek; Gawelda, Wojciech; Bauer, Matthias published an article in 2021. The article was titled 《Fundamental Characterization, Photophysics and Photocatalysis of a Base Metal Iron(II)-Cobalt(III) Dyad》, and you may find the article in Chemistry – A European Journal.Name: 4-Iodopyridine The information in the text is summarized as follows:

A new base metal iron-cobalt dyad has been obtained by connection between a heteroleptic tetra-NHC iron(II) photosensitizer combining a 2,6-bis[3-(2,6-diisopropylphenyl)imidazol-2-ylidene]pyridine with 2,6-bis(3-methyl-imidazol-2-ylidene)-4,4′-bipyridine ligand, and a cobaloxime catalyst. This novel iron(II)-cobalt(III) assembly has been extensively characterized by ground- and excited-state methods like X-ray crystallog., X-ray absorption spectroscopy, (spectro-)electrochem., and steady-state and time-resolved optical absorption spectroscopy, with a particular focus on the stability of the mol. assembly in solution and determination of the excited-state landscape. NMR and UV/Vis spectroscopy reveal dissociation of the dyad in acetonitrile at concentrations below 1 mM and high photostability. Transient absorption spectroscopy after excitation into the metal-to-ligand charge transfer absorption band suggests a relaxation cascade originating from hot singlet and triplet MLCT states, leading to the population of the 3MLCT state that exhibits the longest lifetime. Finally, decay into the ground state involves a 3MC state. Attachment of cobaloxime to the iron photosensitizer increases the 3MLCT lifetime at the iron center. Together with the directing effect of the linker, this potentially makes the dyad more active in photocatalytic proton reduction experiments than the analogous two-component system, consisting of the iron photosensitizer and Co(dmgH)2(py)Cl. This work thus sheds new light on the functionality of base metal dyads, which are important for more efficient and sustainable future proton reduction systems.

Synthetic Route of C5H4INIn 2020 ,《A new class of ratiometric small molecule intracellular pH sensors for Raman microscopy》 appeared in Analyst (Cambridge, United Kingdom). The author of the article were Wilson, Liam T.; Tipping, William J.; Jamieson, Lauren E.; Wetherill, Corinna; Henley, Zoe; Faulds, Karen; Graham, Duncan; Mackay, Simon P.; Tomkinson, Nicholas C. O.. The article conveys some information:

Intracellular pH (pHi) homeostasis is intertwined with a myriad of normal cellular behaviors as well as pathol. processes. As such, small mol. probes for the measurement of pHi are invaluable tools for chem. biol., facilitating the study of the role of pH in cellular function and disease. The field of small mol. pHi sensors has traditionally been dominated with probes based on fluorescent scaffolds. In this study, a series of low mol. weight (<260) oligoyne compounds have been developed which exhibit pH sensitive alkyne stretching frequencies (νalkyne) in Raman spectroscopy. The modular design of the compounds enabled tuneability of their pKa(H) through simple structural modification, such that continuous pH sensitivity is achieved over the range 2-10. Alkyne stretching bands reside in the ′cell-silent′ region of the Raman spectrum (1800-2600 cm-1) and are readily detectable in a cellular environment with subcellular spatial resolution This enabled the application of a pH sensitive oligoyne compound to the ratiometric sensing of pHi in prostate cancer (PC3) cells in response to drug treatment. We propose that probes based on Alkyne Tag Raman Imaging offer an entirely new platform for the sensing of pHi, complementary to fluorescence microscopy.

Zurakowski, Joseph A.; Austen, Brady J. H.; Dufour, Maeve C.; Spasyuk, Denis M.; Nelson, David J.; Drover, Marcus W. published an article in 2021. The article was titled 《Lewis Acid-Promoted Oxidative Addition at a [Ni0(diphosphine)2] Complex: The Critical Role of a Secondary Coordination Sphere》, and you may find the article in Chemistry – A European Journal.Electric Literature of C5H4IN The information in the text is summarized as follows:

Oxidative addition represents a critical elementary step in myriad catalytic transformations. Here, the importance of thoughtful ligand design cannot be overstated. In this work, we report the intermol. activation of iodobenzene (PhI) at a coordinatively saturated 18-electron [Ni0(diphosphine)2] complex bearing a Lewis acidic secondary coordination sphere. Whereas alkyl-substituted diphosphine complexes of Group 10 are known to be unreactive in such reactions, we show that [Ni0(P2BCy4)2] (P2BCy4=1,2-bis(di(3-dicyclohexylboraneyl)-propylphosphino)ethane) is competent for room-temperature PhI cleavage to give [NiII(P2BCy4)(Ph)(I)]. This difference in oxidative addition reactivity has been scrutinized computationally – an outcome that is borne out in ring-opening to provide the reactive precursor – for [Ni0(P2BCy4)2], a “”boron-trapped”” 16-electron κ1-diphosphine Ni(0) complex. Moreover, formation of [NiII(P2BCy4)(Ph)(I)] is inherent to the P2BCy4 secondary coordination sphere: treatment of the Lewis adduct, [Ni0(P2BCy4)2(DMAP)8] with PhI provides [NiII(P2BCy4)2(DMAP)8(I)]I via iodine-atom abstraction and not a [NiII(Ph)(I)(diphosphine)] compound – an unusual secondary sphere effect. Finally, the reactivity of [Ni0(P2BCy4)2] with 4-iodopyridine was surveyed, which resulted in a pyridyl-borane linked oligomer. The implications of these outcomes are discussed in the context of designing strongly donating, and yet labile diphosphine ligands for use in a critical bond activation step relevant to catalysis. In addition to this study using 4-Iodopyridine, there are many other studies that have used 4-Iodopyridine(cas: 15854-87-2Electric Literature of C5H4IN) was used in this study.
