本文对一系列含氰烯类化合物和对-甲基二甲基苯胺(DMT)所组成体系的吸收光谱、荧光光谱以及光致电导行为进行了研究。实验表明:甲基丙烯腈和丙烯腈与DMT间在光照下确是生成了激基络合物,而富马二腈、四氰乙烯和DMT组成的体系,则因体系离子化程度增大,因而未能从光谱中发现激基络合物的存在。光致电导的测定可进一步对体系之离子化提供确切的证据,并能补充吸收光谱和荧光光谱在研究本问题时之不足。 In this paper, the absorption spectra, fluorescence spectra and photoconductive conductances of a series of systems containing cyanide compounds and p-methyldimethylaniline (DMT) were studied. Experiments show that: Methacrylonitrile and acrylonitrile and DMT in the light is indeed generated excimer complex, and fumaronitrile, tetracyanoethylene and DMT system, the system due to the degree of ionization increases, Thus failing to find the existence of exciplex from the spectrum. Photoconductive measurements provide further evidence of ionization of the system and complement the inadequacies of absorption and fluorescence spectroscopy in the study of this problem.
