The synthesis and emissive properties of bichromophoric molecules are reported. All systems contain an anilino group as a one-electron donor (D) and various substituted ethylene moieties as electron acceptor (A) separated by a rod-shaped alicyclic framework provide by a piperidine ring. From the emissive properties it is concluded that in these molecules the electronic coupling between D and A is sufficient
报道了双发色分子的合成和发射特性。所有系统都包含一个
苯胺基作为单电子供体 (D) 和各种取代的亚乙基部分作为电子受体 (A),它们被由
哌啶环提供的棒状脂环骨架隔开。从发射特性可以得出结论,在这些分子中,D 和 A 之间的电子耦合足以在激发时允许完全电荷转移(如果热力学可行)
