The cheap and easily available o-aminophenols (OAPs) have been identified as practical directing component for the Pd-catalyzed aromatic γ-C-H bond arylation of phenylacetamides. Notably, the selective single and double arylation of the C-H bond(s) in the γ-potion has been independently realized by simply modifying reaction conditions. The catalytic system of Pd(CF3OO)2/K2S2O8/K2CO3 enables the selective single C-H arylation. On the other hand, the catalysis of Pd(OAc)2 in the presence of KIO3/K2CO3 induces the selective arylation of both γ-C-H bonds. The experimental part of the paper was very detailed, including the reaction process of 1-Bromo-4-iodobenzene(cas: 589-87-7SDS of cas: 589-87-7)

In 2019,Journal of Physical Chemistry C included an article by Liu, Yifan; Zhang, Xiaomin; Li, Chen; Tian, Yuqi; Zhang, Fengyu; Wang, Yajun; Wu, Wenjun; Liu, Bo. Computed Properties of C6H4BrI. The article was titled 《Energy-Level Control via Molecular Planarization and Its Effect on Interfacial Charge-Transfer Processes in Dye-Sensitized Solar Cells》. The information in the text is summarized as follows:

As the critical property of the organic dye, the energy level determines the thermodn. possibilities and the efficiencies of multiple interfacial charge-transfer processes in dye-sensitized solar cells. Thus, a suitable energy level is highly required, and selective energy control becomes a quite important and systemic objective. Herein, a novel planar carbazole unit, which is synthesized through simple aryl immobilization, is applied as the donor segment in the D-A-π-A organic dye. The considerable dihedral angle between benzene and carbazole is almost eliminated, thus resulting in effective improvement of mol. planarity. As the planarity of donor segment enhances, the HOMO level of the dye increases, whereas its LUMO level remains around the same value, with respect to the twisted dye. Besides, with good mol. planarity, the interfacial charge-transfer processes, including charge injection, charge recombination, and dye regeneration, are efficiently improved. Consequently, the optimization of mol. planarity can selectively control the energy level of the dye, while multiple interfacial charge-transfer processes can also be finely optimized, providing a reasonable strategy to develop an efficient organic sensitizer with long-term photostability.

In this work, polymers of poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-triphenylamine] with side chains containing: pyrene (C1), di-Ph (C2), naphthalene (C3), and iso-Pr (C6) structures were synthesized via a Suzuki coupling reaction. The structures were verified using NMR and cyclic voltammetry measurements provide the HOMO and LUMO of the polymers. The polymer with pyrene (C1) and naphthalene (C3) produced photoluminescence in the green while the polymer with the side chain containing di-Ph (C2) and iso-Pr (C6) produce dual emission peaks of blue-green photoluminescence (PL). In order to examine the electroluminescence properties of the polymers, the solutions were spin-coated onto patterned ITO anode, dried, and subsequently coated with an Al cathode layer to form pristine single layer polymer LEDs. The results are compared to a standard PFO sample. The electroluminescence spectra resemble the PL spectra for C1 and C3. The devices of C2, C3, and C6 exhibit voltage-dependent EL. An addnl. red emission peak was detected for C2 and C6, resulting in spectra with peaks at 435 nm, 490 nm, and 625 nm. The effects of the side chains on the spectral characteristics of the polymer are discussed.

Wang, Yunsheng; Yang, Jie; Fang, Manman; Gong, Yanxiang; Ren, Jia; Tu, Liangjing; Tang, Ben Zhong; Li, Zhen published an article in 2021. The article was titled 《New Phenothiazine Derivatives That Exhibit Photoinduced Room-Temperature Phosphorescence》, and you may find the article in Advanced Functional Materials.Electric Literature of C6H4BrI The information in the text is summarized as follows:

The research of purely organic room-temperature phosphorescence (RTP) materials with stimulus response characteristic has drawn increasing attention for their broad application prospects. However, these kinds of materials are really scarce now, especially for those with efficient RTP emissions, which have largely limited their practical applications. Here, an all-around-type player in the field of photoinduced phosphorescence material appears, whose RTP efficiency can increase from near 0 to 22% after continuous UV irradiation Correspondingly, the UV-written patterns based on them can be clearly observed by the naked eye in daytime or even under sunlight. Moreover, these materials are found to show excellent photostability, and the strong RTP emission can still be observed after repeated activation for more than 50 times. The high RTP efficiency and good photostability make these photoinduced RTP materials exhibit an attractive prospect for potential applications in many fields, including leak test, microcrack detection, programmable information storage, and encryption.

The title of the article was 《Deciphering the reduced loss in high fill factor inverted perovskite solar cells with methoxy-substituted poly(triarylamine) as the hole selective contact》.COA of Formula: C6H4BrI The author mentioned the following in the article:

A dopant-free polymeric hole selective contact (HSC) layer is ubiquitous for stable perovskite solar cells (PSCs). However, the intrinsic nonwetting nature of the polymeric HSC impedes the uniform spreading of the perovskite precursor solution, generating a terrible buried interface. Here, we dexterously tackle this dilemma from the perspective of dispersive and polar component surface energies of the HSC layer. A novel triarylamine-based HSC material, poly[bis(4-phenyl)(2,4-dimethoxyphenyl)amine] (2MeO-PTAA), was designed by introducing the polar methoxy groups to the para and ortho positions of the dangling benzene. These nonsym. substituted electron-donating methoxy groups enhanced the polar components of surface energy, allowing more tight interfacial contact between the HSC layer and perovskite and facilitating hole extraction When utilized as the dopant-free HSC layer in inverted PSCs, the 2MeO-PTAA-based device with CH3NH3PbI3 as the absorber exhibited an encouraging power conversion efficiency of 20.23% and a high fill factor of 84.31% with negligible hysteresis. Finally, a revised detailed balance model was used to verify the drastically lessened surface defect-induced recombination loss and shunt resistance loss in 2MeO-PTAA-based devices. This work demonstrates a facile and efficient way to modulate the buried interface and shed light on the direction to further improve the photovoltaic performance of inverted PSCs with other types of perovskites.

《Balancing Charge Transfer and Frenkel Exciton Coupling Leads to Excimer Formation in Molecular Dimers: Implications for Singlet Fission》 was published in Journal of Physical Chemistry A in 2020. These research results belong to Bae, Youn Jue; Shimizu, Daiki; Schultz, Jonathan D.; Kang, Gyeongwon; Zhou, Jiawang; Schatz, George C.; Osuka, Atsuhiro; Wasielewski, Michael R.. Formula: C6H4BrI The article mentions the following:

Photoexcitation of mol. chromophore aggregates can form excimer states that play a significant role in photophys. processes such as charge and energy transfer as well as singlet fission. An excimer state is commonly defined as a superposition of Frenkel exciton and charge transfer states. The dynamics were studied of excimer formation and decay in π-stacked 9,10-bis(phenylethynyl)anthracene (BPEA) covalent dimers appended to a xanthene spacer, where the electronic coupling between the 2 BPEA mols. is adjusted by changing their longitudinal mol. slip distances. Using exciton coupling calculations, the authors quantify the relative contributions of Frenkel excitons and charge transfer states and find that there is an upper and lower threshold of the charge transfer contribution for efficient excimer formation to occur. Knowing these thresholds can aid the design of mol. aggregates that optimize singlet fission. In addition to this study using 1-Bromo-4-iodobenzene, there are many other studies that have used 1-Bromo-4-iodobenzene(cas: 589-87-7Formula: C6H4BrI) was used in this study.
