reaction was used to construct a series of α‐cyano‐α,ω‐diaryloligovinylenes, which show prominent fluorescence emission in the solid state. On investigating the effect of conjugation length on fluorescent properties, we found that the diene structure showed superior solid‐state luminescence. Furthermore, the emission color could be adjusted by introducing donor or acceptor functional groups at the
有效的Knoevenagel缩合反应用于构建一系列的α-氰基-α,ω-二芳基寡聚谷氨酰胺,它们在固态下显示出显着的荧光发射。在研究共轭长度对荧光性质的影响时,我们发现二烯结构显示出优异的固态发光。此外,可以通过在末端芳基上引入供体或受体官能团来调节发光颜色。通过向α-氰基-α,ω-二芳基二亚乙烯基部分添加不同的官能团,可以实现可见光区域的全色发射。阐明了结构与属性之间的关系,并讨论了一些观察结果,例如取代位置效应。
