摘　　要：本文设计合成了三个以不同链长相连接的蒽－对二氰基乙烯基苯（Ａｎ－ＤＣＶＢ）化合物。利用吸收光谱，荧光光谱，激光闪光光解和单光子计数器等证实Ａｎ－ＤＣＶＢ受光激发，发生分子内电子转移，生成激基复合物且发现有三重态能量传递，描述了分子内电子转移的主要途径，研究并探讨了Ａｎ－ＤＣＶＢ的三种不同连接链长对分子构象，激基复合物的形成以及三重态能量传递的影响。Three anthracene-dicyanovinylbenzene compounds with different length spacer were designed and synthesized. The mechanism of the intramolecular electron transfer of An-DCVB was investigated with absorption, fluorescence spectra,laser flash photolysis and single photon counting. Upon irradiation, intramolecular electron transfer from moiety An to DCVB occurred, exciplex formed and triplet energy transfer took place.The influences of thelength spacer on molecular conformation, exciplex formation and triplet energy transfer werediscussed.
