Utilizing 1,10-phenanthroline-type bifunctional ligands, an efficient Cu-catalyzed intermolecular site-selective remote C–H amination using cyclohexenonederivatives and anilines was realized. The amide group installed on the bifunctional ligand played a key role in stabilizing the N-centered radical generated in situ to realize C–N-directed formation. Meanwhile, a useful catalytic system for site-selective
利用 1,10-菲咯啉型双功能配体,实现了使用环己烯酮衍生物和苯胺的高效铜催化分子间位点选择性远程 C-H 胺化。安装在双功能配体上的酰胺基团在稳定原位产生的 N 中心自由基以实现 C-N 定向形成方面发挥了关键作用。同时,建立了一个有用的催化体系,用于位点选择性分子间远程γ-C-H胺化对氨基苯酚和γ-胺化烯酮。这种使用氧气作为终端氧化剂的经济实用方法温和且环保。

The invention provides an anthracene-based organic dye and a preparation method thereof. The organic dye provided by the invention has a structure of formula (I) or formula (II), wherein Ra, Rb, and R2-1 to R2-4 are as defined herein. The organic dye provided by the invention is obtained by modifying an anthracene with Ra and Rb or modifying anthracene-based groups decorated with an aryl group or a heteroaryl group with Ra and Rb, thereby the power conversion efficiency of a dye sensitized solar cell is significantly improved when the organic dye prepared according to the present invention is applied in a dye-sensitized solar cell. Furthermore, the preparation method of the organic dye according to the present invention is quite simple together with abundant raw materials and low cost, making it possible to be commercialized.
