Symmetrical and unsymmetrical 4,4′-biphenyl, and 9,10-anthracene derivatives with tris(trifluoromethyl)germylethynyl –CC–Ge(CF3)3 substitutes have been prepared, their properties have been studied and compared with those of dimethyl(phenyl)silylethynyl –CC–Si(Ph)Me2 compounds. UV–visible absorption, steady-state, and time-resolved fluorescence spectra in solution for this germanium and silicon compounds
制备了具有三(三氟甲基)甲基乙炔基-C C-Ge(CF 3)3取代基的对称和不对称的4,4'-联苯和9,10-蒽衍生物,并对其性质进行了研究,并与二甲基(苯基)甲硅烷基乙炔基-C C-Si(Ph)Me 2化合物。研究了该锗和硅化合物在溶液中的紫外可见吸收,稳态和时间分辨荧光光谱。在不对称的4-联苯基-C C-Ge(CF 3)3分子中发现了光诱导电子从芳族基团转移到锗中心的过程。具有–C C – Ge(CF 3)的蒽衍生物在晶体学上已经表征了3个替代品。
