Photoinduced electron transfer in a series of naphthyl substituted phenanthrimidazoles has been studied in solutions. The intramolecular charge transfer (CT) leads to a large Stokes shift and large dipole moment in the fluorescent state. Solvatochromic effects on the spectral position and profile of the stationary fluorescence spectra clearly indicate the CT character of the emitting singlet states of all the compounds studied. An analysis of the CT fluorescence lead to the quantities relevant for the electron transfer in the Marcus inverted region.
已在溶液中研究了一系列萘基取代菲并咪唑中的光致电子转移。分子内电荷转移（CT）导致荧光态下出现大的斯托克斯位移和大的偶极矩。溶剂化显色效应作用于稳态荧光光谱的光谱位置和轮廓，清楚地表明了所有研究化合物发射单重态的CT特性。对CT荧光的分析得出了与马库斯反转区域中电子转移相关的量。
