摘要：

Fluorescence-excitation and fluorescence spectra, as well as fluorescence decay times, are recorded for anthracene-N,N-dimethylaniline (DMA) and anthracene-N,N-diethylaniline (DEA) complexes excited in their 000 and 000+385 cm-1 spectral regions. Their excitation spectra are composed of overlapping narrow-band and broad-band systems tentatively assigned to two isomeric forms, with the lowest excited state of van der Waals (A*D) and ionic (A-D+) character. The dual fluorescence (A*D→AD) and (A-D+→AD) with intensity ratio strongly varying from level to level was observed upon the selective excitation of the van der Waals form of the DEA complex. Possible mechanisms of isomerization are discussed. © 1990.
