decay pathways were investigated theoretically. Bridged stilbenes with short alkyl chains exhibited a strong fluorescence emission in solution and in the solid state, while bridged stilbenes with long alkyl chains exhibited AIE. Based on this theoretical prediction, we developed the bridged stilbenes BPST[7] and DPB[7], which demonstrate excellent AIE behavior.
拓宽聚合诱导的发射(AIE)luminogens(AIEgens)的应用,显示出高荧光量子产率(Φ新型小分子染料的设计FL需要在固体状态)。考虑到可以基于空间上避免非辐射衰变途径来合理化AIE的机理,设计了一系列桥连对苯二酚,并对它们的非辐射衰变途径进行了理论研究。具有短烷基链的桥墩石es素在溶液和固态下均表现出较强的荧光发射,而具有长烷基链的桥墩石til素具有AIE。基于这一理论预测,我们开发了桥接的斯蒂芬酯BPST [7]和DPB [7],它们表现出优异的AIE行为。
