摘　　要：本工作研究了几种中心部分被束缚的双[对一N,N-二甲基氨基苄叉]酮类化合物的光物理行为.发现中心五元环的化合物比中心六元环的化合物有着高得多的荧光量子产率.在改变介质粘度、研究粘度对荧光量子产率的影响时发现中心六元环化合物最易受粘度变化的影响.对上述这些有趣的现象进行了扼要的分析和讨论.In this article, the photophysical behaviors of several kinds of bis[p-N.N-dimethyl aminobenzylidene] ketone compounds in which the central parts of molecules are restricted have been investigated. It has been found that compound with central five member ring possesses higher fluorescence quantum yield than that of central six member ring. As for the effect of medium viscosity on the fluorescenee quantum yields of these compounds, it was discovered that compound with central six member ring is the most susceptible one to the change of medium viscosity. All of these interesting phenomenon have been discussed briefly.
