In 2019,Journal of Organic Chemistry included an article by Pramanick, Pranab K.; Zhou, Zhibing; Hou, Zhen-Lin; Yao, Bo. Application In Synthesis of 1-Bromo-4-iodobenzene. The article was titled 《Free Amino Group-Directed γ-C(sp3)-H Arylation of α-Amino Esters with Diaryliodonium Triflates by Palladium Catalysis》. The information in the text is summarized as follows:

Free amino group-directed C(sp3)-H functionalization of aliphatic amines is a fundamental challenge in synthetic organic chem. Also, the NH2-directed C(sp3)-H functionalization of α-amino acids and their derivatives remains barely explored. With palladium as the catalyst and Ag2O as the additive, the authors developed the first NH2-directed γ-C(sp3)-H arylation of α-amino esters with diaryliodonium triflates for the construction of synthetically useful γ-aryl-α-amino esters, and the result of the KIE study suggested that the catalytic reaction involved an irreversible C-H cleavage as the rate-determining step.

Lee, Jian Haur; Lin, Hung-Yi; Chen, Chia-Hsun; Lee, Yi-Ting; Chiu, Tien-Lung; Lee, Jiun-Haw; Chen, Chin-Ti; Adachi, Chihaya published their research in ACS Applied Materials & Interfaces in 2021. The article was titled 《Deep Blue Fluorescent Material with an Extremely High Ratio of Horizontal Orientation to Enhance Light Outcoupling Efficiency (44%) and External Quantum Efficiency in Doped and Non-Doped Organic Light-Emitting Diodes》.SDS of cas: 589-87-7 The article contains the following contents:

A novel bis-4Ph-substituted 9,10-dipehnylanthracene deep blue [1931 CIE (0.15, 0.08)] fluorescent compound, AnB4Ph, has been synthesized and characterized for organic light-emitting diode (OLED) applications. Our exptl. study of AnB4Ph excludes the possibility of triplet-triplet annihilation, hybridized local and charge transfer, or thermally activated delayed fluorescent characteristics of the material. Since the solid-state photoluminescence quantum yield of AnB4Ph was determined to be 48%, assuming a 100% for the charge recombination efficiency, the light outcoupling efficiency (ηout) of an AnB4Ph non-doped OLED achieving an external quantum efficiency (EQE) of 5.3% is at least 44%, which is more than twofold higher than 20% for conventional OLEDs. Both grazing incidence wide-angle X-ray scattering (GIWAXS) and angle-dependent photoluminescence (ADPL) measurements reveal AnB4Ph having a high value of order parameter (SGIWAXS) of 0.61 for a ππ stacking along the normal direction and an orientation order parameter (SADPL) for a horizontal emitting dipole moment of -0.50 or Θ (horizontal-dipole ratios) of 100%, resp. Otherwise, a refractive index (n) measurement provides a n = 1.80 for AnB4Ph thin films. Based on ηout = 1.2 x n-2, the calculated ηout is 37%, which is also in accordance with the results of GIWAXS and ADPL. We have also fabricated the classical fluorescent DPAVBi-doped AnB4Ph OLEDs, which display a true blue [1931 CIE (0.15 and 0.16)] electroluminescence with a high efficiency (EQE = 6.9%), surpassing the conventional ~5% EQE. Based on an ηout of 42% for DPAVBi-doped AnB4Ph OLEDs, our studies suggest that the extremely horizontally aligned AnB4Ph host material exerts the same horizontal alignment on the DPAVBi dopant mols.

Chen, Yi; Chang, Kai-Hsin; Meng, Fan-Yi; Tseng, Sheng-Ming; Chou, Pi-Tai published their research in Angewandte Chemie, International Edition in 2021. The article was titled 《Broadening the Horizon of the Bell-Evans-Polanyi Principle towards Optically Triggered Structure Planarization》.Quality Control of 1-Bromo-4-iodobenzene The article contains the following contents:

Finding a relationship between kinetics and thermodn. may be difficult. However, semi-empirical rules exist to compensate for this shortcoming, among which the Bell-Evans-Polanyi (B-E-P) principle is an example for reactions involving bond breakage and reformation. We expand the B-E-P principle to a new territory by probing photoinduced structure planarization (PISP) of a series of dibenz[b,f]azepine derivatives incorporating bent-to-planar and rotation motion. The latter involves twisting of the partial double bond character, thereby inducing a barrier that is substituent dependent at the para N-Ph position. The transition-state structure and frequency data satisfy and broaden the B-E-P principle to PISP reactions without bond rearrangement. Together with dual emissions during PISP, this makes possible harnessing of the kinetics/thermodn. relationship and hence ratiometric luminescence properties for excited-state structural transformations.

A series of small-mol.-based hole-transporting materials (HTMs) featuring a 4H-cyclopenta[2,1-b : 3,4-b]dithiophene as the central core with triphenylamine- and carbazole-based side groups was synthesized and evaluated for perovskite solar cells. The correlations of the chem. structure of the HTMs on the photovoltaic performance were explored through different combinations of the central π-bridge moieties. The optical and electrochem. properties, energy levels, and hole mobility were systematically investigated, revealing the significant influence of the central core planarity and packing structure on their photovoltaic performance. The optimized device based on CT1 exhibited a PCE (power conversion efficiency) of 17.71% with a device architecture of FTO/TiO2 compact layer/TiO2 mesoporous/CH3NH3PbI3/HTM/MoO3/Ag, which was found to be on par with that of a cell fabricated based on state-of-the-art spiro-OMeTAD (16.97%) as HTM. Moreover, stability assessment showed an improved stability for CPDT-based HTMs in comparison with spiro-OMeTAD over 1300 h.

Reference of 1-Bromo-4-iodobenzene And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:

Solid-state materials with efficient room-temperature phosphorescence (RTP) emissions have found widespread applications in materials science, while liquid or solution-phase pure organic RTP emission systems has been rarely reported, because of the nonradiative decay and quenchers from the liquid medium. Reported here is the first example of visible-light-excited pure organic RTP in aqueous solution by using a supramol. host-guest assembly strategy. The unique cucurbit[8]uril-mediated quaternary stacking structure allows tunable photoluminescence and visible-light excitation, enabling the fabrication of multicolor hydrogels and cell imaging. The present assembly-induced emission approach, as a proof of concept, contributes to the construction of novel metal-free RTP systems with tunable photoluminescence in aqueous solution, providing broad opportunities for further applications in biol. imaging, detection, optical sensors, and so forth.1-Bromo-4-iodobenzene(cas: 589-87-7Reference of 1-Bromo-4-iodobenzene) was used in this study.

The article was titled 《Convenient Access to Chiral Cyclobutanes with Three Contiguous Stereocenters from Verbenone by Directed C(sp3)-H arylation》. The information in the text is summarized as follows:

This work demonstrates how a series of complex, chiral cyclobutane derivatives can be accessed in four steps from the terpene verbenone through the application of a directed C-H functionalization approach. The developed synthetic route involved an 8-aminoquinoline-directed C(sp3)-H arylation as the key step, and this reaction could be carried out with a wide range of aryl and heteroaryl iodides to furnish a variety of cyclobutane products I (Ar = Ph, 4-ClC6H4, 2-thienyl, etc.; Q = quinolin-8-yl) with three contiguous stereocenters. Moreover, it was shown that the 8-aminoquinoline auxiliary could be effectively removed from the cyclobutane derivatives using an ozonolysis-based cleavage method.

The author of the article were Li, Penghao; Chen, Zhijie; Ryder, Matthew R.; Stern, Charlotte L.; Guo, Qing-Hui; Wang, Xingjie; Farha, Omar K.; Stoddart, J. Fraser. The article conveys some information:

Herein we report a hydrogen-bonded three-dimensional porous supramol. polyknot assembled from a rigid trigonal prismatic triptycene building block with six extended peripheral aryl-carboxyl groups. Within this superstructure, three arrays of undulated 2D rhombic subnets, which display an inclined polycatenation, are interconnected to give an unprecedented uninodal six-connected net with a point symbol of (3.44.610).
