4,6-triisopropylphenyl)phenyl}diphosphene (1), possessing two bis(4-methoxyphenyl)amino groups as redox sites as well as electron-donating sources, was synthesized and isolated as a red solid. The cyclic voltammogram of 1 at −78° consisted of three reversible redox waves corresponding to two-step oxidation of the triarylamine moieties and reduction of the diphosphene moiety. Introduction of the two
双4-[双(4-甲氧基苯基)氨基]-2,6-双(2,4,6-三异丙基苯基)苯基}二膦(1),同时具有两个双(4-甲氧基苯基)氨基作为氧化还原位点作为给电子源,合成并分离为红色固体。-78°处的1的循环伏安图由三个可逆氧化还原波组成,对应于三芳胺部分的两步氧化和二膦部分的还原。两个氨基的引入也导致 UV/VIS 光谱中最大吸收的红移,这导致了 1 的强烈红色。
