合成了一系列中氮茚化合物,研究了化合物3a～3k,4a～4b,5～6分子中不同取代基对其荧光光谱和荧光量子效率的影响.发现中氮茚环上的氰基具有较好的荧光助色作用,中氮茚环上的COPh,COMe或CHO对分子的荧光具有猝灭作用;发现中氮茚类有机化合物的分子结构与荧光性质之间的某些关系.化合物3a～3b,3g～3i具有较高的荧光量子效率,可以作为比较好的有机荧光分子用于探针化合物的结构修饰.

关键词: 中氮茚, 荧光光谱, 荧光量子效率

A series of indolizines were synthesized.The fluorescence spectra and fluorescence quantum yields of the compounds 3a～3k, 4a～4b and 5～6 were examined.It was found that the quantum yields increased if the cyano group was introduced into the indolizines, while the presence of carbonyl groups as substituents of indolizines resulted in fluorescence quenching.The indolizines 3a～3b and 3g～3i with high fluorescence quantum yields are shown to be useful fluorophores to the construction of probe compounds.

Key words: indolizine,fluorescence spectrum,fluorescence quantum yield
