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. The results came from multiple reactions, including the reaction of 1-Bromo-4-iodobenzene(cas: 589-87-7Computed Properties of C6H4BrI)
1-Bromo-4-iodobenzene(cas: 589-87-7) has been employed as reagent for in situ desilylation and coupling of silylated alkynes, as starting reagent in the total syntheses of ent-conduramine A and ent-7-deoxypancratistatin (alkaloids), as substrate in copper-free Sonogashira coupling in aqueous acetone in synthesis of β,β,dibromostyrenesComputed Properties of C6H4BrI
