摘　　要：设计合成一系列具有不同取代基的苯甲酰萘 (苯 )胺衍生物 ,测定它们在非极性溶剂环己烷中的荧光发射光谱。发现系列合成产物具有双重荧光 ,其长波发射具有电荷转移特性 ,其长波发射态能量与不同取代基的苯甲酰萘 (苯 )胺衍生物的失 (得 )电子能力 ,即给 (受 )体的氧化还原电位之间符合Weller方程。A series of prar-and meta-substituted benzanilides were synthesized and their fluorescence spectra in nonpolar solvent cyclohexane were investigated. It was observed that all the synthesized compounds displayed dual fluorescence in cyclohexane and an abnomal long-wavelength emission originated from intramolecular charge transfer state. The relationship of long-wavelength emission energies with donor (acceptor) potentials conform to Weller equation.
