Fifteen 4-(2-methoxyphenyl)piperazin-1-ium salts containing organic anions have been prepared and structurally characterized. In the isostructural 4-chlorobenzoate and 4-bromobenzoate salts, C11H17N20+·C7H4ClO2- (I) and C11H17N20+·C7H4BrO2- (II), and the 4-iodobenzoate salt C11H17N20+·C7H4IO2- (III), the ions are linked by N-H···O hydrogen bonds, forming centrosym. R44(12) four-ion aggregates; a similar aggregate is formed in the 2-chlorobenzoate salt (V), isomeric with (I). In the 2-fluorobenzoate salt C11H17N2O+·C7H4FO2- (IV), and the isomorphous pair of salts, the 2-bromobenzoate (VI), isomeric with (II) and 2-iodobenzoate (VII), isomeric with (III), N-H···O and C-H···π(arene) interactions link the components into three-dimensional arrays. Four-ion R44(12) aggregates are also found in the 2-methylbenzoate, 4-aminobenzoate and 4-nitrobenzoate salts, C11H17N2O+·C8H7O2- (VIII), C11H17N2O+·C7H6NO2- (IX) and C11H17N2O+·C7H4NO4- (X), but those in (IX) are linked into complex sheets by an addnl. N-H···O hydrogen bond. In the 3,5-dinitrobenzoate salt, C11H17N2O+·C7H3N2O6-·2H2O (XI), N-H···O and O-H···O hydrogen bonds link the components into a complex ribbon structure. In the picrate salt, C11H17N2O+·C6H2N3O7- (XII), the four-ion aggregates are linked into chains of rings by C-H···O hydrogen bonds. In the hydrogen maleate salt, C11H17N2O+·C4H3O4- (XIII), two- and three-center hydrogen bonds link the ions into a ribbon structure while both anions contain very short but asym. O-H···O hydrogen bonds, having O···O distances of 2.4447 (16) and 2.4707 (17) Å. O-H···O Hydrogen bonds link the anions in the hydrogen fumarate salt (XIV), isomeric with (XIII), into chains that are linked into sheets via N-H···O hydrogen bonds. In the hydrogen (2R,3R)-tartrate salt, C11H17N2O+·C4H5O6-·1.698H2O (XV), the anions are linked into sheets by O-H···O hydrogen bonds.

In 2015,Guo, Haiquan; Liu, Fangfang; Zhao, Jianying; Yao, Haibo; Jin, Rizhe; Kang, Chuanqing; Bian, Zheng; Qiu, Xuepeng; Gao, Lianxun published 《In situ iodoalkane-reduction of graphene oxide in a polymer matrix: an easy and effective approach for the fabrication of conductive composites》.Journal of Materials Chemistry C: Materials for Optical and Electronic Devices published the findings.Related Products of 624-73-7 The information in the text is summarized as follows:

In situ chem. reduction (ISCR) of graphene oxide (GO) dispersed in a polymer matrix has been regarded as an effective path to fabricate elec. conductive graphene/polymer composites due to the combination of perfect dispersion of GO in a polymer matrix and high elec. conductivity of graphene. However, there are only very limited number of reducing agents that can be applied to the ISCR process for the fabrication of graphene/polymer composites. Herein, we report a highly efficient reducing agent, 1,2-diiodoethane, which can be used in the preparation of graphene (IGO)/polyimide (PI) composites via the ISCR process. The results showed that the elec. conductivity of IGO/PI composites with 2.5 wt% of IGO was 2.22 S m-1, nearly seven orders of magnitudes higher than that of GO/PI without the addition of 1,2-diiodoethane. Moreover, the tensile strength and modulus of IGO/PI composites were increased by about 43% and 52% as compared with that of the pure PI, resp. Furthermore, 1,2-diiodoethane and its decomposition products would not remain in the composites. The ISCR-based methodol. can be extended to many other polymer composites and thus paves the way for easy and effective fabrication of conductive polymer composites. In addition to this study using 1,2-Diiodoethane, there are many other studies that have used 1,2-Diiodoethane(cas: 624-73-7Related Products of 624-73-7) was used in this study.

1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Related Products of 624-73-7

Safety of 4-Iodobenzoic acid The author mentioned the following in the article:

The direction of electron flow in mol. optoelectronic devices is dictated by charge transfer between a mol. excited state and an underlying conductor or semiconductor. For those devices, controlling the direction and reversibility of electron flow is a major challenge. We describe here a single-mol. photodiode. It is based on an internally conjugated, bichromophoric dyad with chem. linked (porphyrinato)zinc(II) and bis(terpyridyl)ruthenium(II) groups. On nanocrystalline, degenerately doped indium tin oxide electrodes, the dyad exhibits distinct frequency-dependent, charge-transfer characters. Variations in the light source between red-light (∼1.9 eV) and blue-light (∼2.7 eV) excitation for the integrated photodiode result in switching of photocurrents between cathodic and anodic. The origin of the excitation frequency-dependent photocurrents lies in the electronic structure of the chromophore excited states, as shown by the results of theor. calculations, laser flash photolysis, and steady-state spectrophotometric measurements.

Feng, Zhao; Yu, Yue; Yang, Xiaolong; Sun, Yuanhui; Zhong, Daokun; Deng, Xuming; Zhou, Guijiang; Wu, Zhaoxin published an article in 2021. The article was titled 《Manipulating MLCT transition character with ppy-type four-coordinate organoboron skeleton for highly efficient long-wavelength Ir-based phosphors in organic light-emitting diodes》, and you may find the article in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices.Safety of 1-Bromo-3-iodobenzene The information in the text is summarized as follows:

Inspired by the intriguing optoelectronic characteristics of the 2-phenylpyridine-type (ppy-type) four-coordinate organoboron skeleton, we envisage a mol. design strategy by manipulating the MLCT transition character to develop high-performance long-wavelength Ir-based phosphors with a ppy-type four-coordinate organoboron skeleton for organic light-emitting diodes (OLEDs). Three ppy-type cyclometalated Ir(III) complexes are successfully prepared IrOBN and IrPBN exhibit the expected long-wavelength phosphorescent emission at 620 and 604 nm, resp., due to the electron-accepting ability of the pyridine coordinated with the boron atom (pyd(B)) in extending the π-conjugated length for the LUMO, thus leading to stabilization of the LUMO. Interestingly, IrMBN shows a green phosphorescence at 514 nm. The more electron-deficient pyd(B) in IrMBN leads to a reorganized and localized LUMO distribution pattern mainly on pyd(B) rather than the pyridine coordinated with the Ir atom (pyd(Ir)), shortening the π-conjugation length for the LUMO, hence resulting in an elevated LUMO. Benefiting from the high rigidity of the ppy-type four-coordinate organoboron skeleton, these three ppy-type cyclometalated Ir(III) complexes show high PLQY (ca. 0.6-1). Beneficially, we can achieve impressive electroluminescence (EL) performance based on IrPBN with the highest efficiencies of a maximum external quantum efficiency (ηext) of 26.0%, a maximum current efficiency (ηL) of 42.0 cd A-1, and a maximum power efficiency (ηP) of 38.5 lm W-1, resp. All these excellent results convincingly demonstrate the effectiveness of our mol. design strategy and the great potential of the ppy-type four-coordinate organoboron skeleton in developing high-performance Ir-based phosphors.

The title of the article was 《A cobalt covalent organic framework: a dual-functional atomic-level catalyst for visible-light-driven C-H annulation of amides with alkynes》.Recommanded Product: 15164-44-0 The author mentioned the following in the article:

Herein, a synthesis of a dual-functional cobalt covalent organic framework (CoCOF-SYNU-1) for visible-light-driven C-H annulation of amides with alkynes was reported. An at.-level cobalt center ensures the occurrence of powerful chelation with amides and subsequent precise C-H activation, while the photoactive covalent organic framework was responsible for absorbing visible light to accelerate the catalytic cycle. In the presence of CoCOF-SYNU-1, visible-light-driven regioselective [4 + 2] C-H annulation proceeded smoothly, delivering a wide range of isoquinolin-1(2H)-one derivatives I [R1 = n-Pr, n-Bu, Ph, etc.; R2 = H, n-Pr, trimethylsilyl, etc.; R3 = H, 6-Me, 8-I, etc.; Q = 8-quinolyl] with high efficiency. Significantly, due to the inherent heterogeneous nature and good stability of CoCOF-SYNU-1, the reaction exhibited excellent catalyst recyclability and practicability.
