discovery of dual fluorescence. Because of their unique photophysical properties, these dual fluorescent systems represent an exception to the widely studied TICT (Twisted Internal Charge Transfer) fluorescent dyes or tautomeric benzofluorescein class of two-color dyes. The matrix library was designed to investigate the effects of heterocycles, particularly π-excessive and π-deficient systems. Of the
合成了一个3×14的取代N-芳基-1,8-萘二甲酰亚胺基质,用于评估和发现双重荧光。由于其独特的光物理特性,这些双荧光系统代表了被广泛研究的TICT(扭曲内部电荷转移)荧光染料或互变异构苯并荧光素类双色染料的例外。矩阵库旨在研究杂环的影响,尤其是π过多和π不足的系统。在接受调查的42种化合物中,有五种在非极性溶剂(如己烷)中显示出良好分辨的双色发射。根据观察到的趋势荧光λ最大以及量子产率,提出了一个新模型来预测这些系统的LW和SW发射。此外,该模型为合成新的双荧光物质提供了潜在的设计特征。
