Small molecules having fluorescence quantum yields are required to promote biological and organic material applications. In this work, we introduced a series of pyridinyl coumarincarboxymides derivatives, namely 4-XP. These compounds exhibited intense blue fluorescence with high fluorescence quantum yield. By spectral measurement and analysis, it is identified that these pyridine-coumarin conjugates
需要具有荧光量子产率的小分子来促进生物和有机材料的应用。在这项工作中,我们介绍了一系列吡啶基香豆素羧酰亚胺衍生物,即4-XP。这些化合物表现出强烈的蓝色荧光和高荧光量子产率。通过光谱测量和分析,确定这些吡啶-香豆素缀合物 在非极性溶剂中在约 455 nm 处显示出高荧光量子产率 (Φ F = 0.77–0.82) 蓝色荧光。此外,溶剂效应和荧光特性通过 DFT 和 TD-DFT 计算得到验证和解释。
