The synthesis and photophysical properties of two novel multichromophoric compounds is presented. Their molecular design comprises a carbonyl‐bridged triarylamine core and either naphthalimides or 4‐(5‐hexyl‐2,2′‐bithiophene)naphthalimides as second chromophore in the periphery. The lateral chromophores are attached to the core via an amide linkage and a short alkyl spacer. The synthetic approach demonstrates
介绍了两种新型多发色化合物的合成和光物理性质。他们的分子设计包括羰基桥联的三芳基胺核和萘二甲酰亚胺或4-(5-己基-2,2'-联噻吩)萘二甲酰亚胺作为周边的第二个生色团。侧生色团通过酰胺键和短烷基间隔基连接到核上。合成方法证明了羰基桥联的三芳基胺的直接官能化策略。这些化合物与三种参考化合物的稳态和时间分辨光谱研究为两种多发色化合物的能量转移提供了清晰的证据。能量转移的方向取决于所用的侧向生色团。此外,
