A series of asymmetric donor–acceptor (D–A) perylene-based compounds, 3-(N,N-bis(4′-(R)-phenyl)amino)perylene (Peri–DPA(R)), were successfully prepared to explore their intramolecular charge transfer (ICT) properties. To induce ICT between the donor and acceptor, diphenylamine (DPA) derivatives (electron donor units) with the same functional groups (R = CN, F, H, Me, or OMe) at both para positions
成功制备了一系列基于不对称供体-受体(DA)ylene的化合物3-(N,N-双(4'-((R)-苯基)氨基)per(Peri - DPA(R))探索它们的分子内电荷转移(ICT)特性。为了在供体和受体之间诱导ICT,将两个对位上具有相同官能团(R = CN,F,H,Me或OMe)的相同官能团的二苯胺(DPA)衍生物(电子供体单元)连接到C-3位置per生产五种Peri – DPA衍生物。Peri – DPA(R的稳态光谱研究)在从吸电子基团向供电子基团发展的过程中表现出与取代效应一致的逐渐调节的ICT趋势。尤其是,使用D-A-D(施主-受主-施主)系统进行的比较研究表明,不仅电子推挽取代基效应而且亚基组合也会影响光物理和电化学性质。在利珀特-又贺曲线中观察到的不同的信息和通信技术的字符d -甲(CN)和d -甲- d(CN)(CN取代d -甲和d -甲- d)导致调查了两个亚单元组合不同的
