The absorption spectra, fluorescence spectra and photoconduction of some systems com-posed of different cyano-containing olefinic compounds and N, N-dimethyl-p-toluidine (DMT)have been studied in this paper. The experimental results show that the exciplex emissionspectra can be observed when the systems of acrylonitrile (AN) or methacrylonitrile (MAN)with DMT are illuminated, whereas the exciplexes between trans-1, 2,-dicyanocthylene(DCNE) or tetracyanoethylene (TONE) with DMT could not be found from the spectra dueto their large ionization. The measurements of photoconduction provide further a clear andunambiguous evidence for the ionization of the systems mentioned above, and they are thesupplement to the systems studied here.
