摘　　要：利用N-乙基咔唑和2-甲基蒽醌合成了一种A-π-D-π-A分子内电荷转移型化合物3,6-二(蒽醌-2-乙烯基)-N-乙基咔唑,并对该化合物的光化学和光物理行为进行了研究。荧光光谱表明,该化合物的发光行为对溶剂的极性非常敏感,随着溶剂极性的增大,其荧光最大发射峰有明显红移,并在强极性溶剂乙腈中出现了双荧光现象。该化合物的激发态和基态的偶极矩差值△μ为3.014D,发生了从给体(咔唑基)的N原子到分子两端受体(蒽醌)的羰基的分子内电荷转移。A novel A-π-D-π-A-type intramolecular charge transfer compound,3,6-bis（anthraquinone-2-vinyl）-Nethyl-carbazole,was synthesised in this paper.The photochemical and photophysical behaviors of this compound were investigated by fluorescence technique.Its maximum emission showed obvious bathochromic shift with the increase of solvent polarity,and dual fluorescence phenomenon appeared in strong polar solvent.The estimated dipole moment difference between the ground and excited state（△μ）was 3.014 D.The intramolecular charge transfer occurred from carbazole donor to carbonyl acceptors.
