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 work, we investigated the photophysical behavior of several bis [p-N, N-dimethylaminobenzylidene] ketone compounds bound to the central part of the compound. It was found that the five- Much more fluorescence quantum yield.Changing the viscosity of the medium and studying the influence of viscosity on the fluorescence quantum yield found that the central 6-membered ring compounds are the most susceptible to viscosity changes.These interesting phenomena above are briefly analyzed and discussed .
