A phenothiazinyl donor moiety can be covalently coupled to aromatic hydrocarbon acceptor units via Ugi four-component reaction in an efficient, rapid, and highly convergent fashion. These novel phenothiazine-acceptor dyads are electronically decoupled in the electronic ground state according to UV/Vis spectroscopy and cyclic voltammetry. In the excited state the inherent acceptor luminescence is substantially
吩噻嗪基供体部分可以通过 Ugi 四组分反应以高效、快速和高度收敛的方式与
芳烃受体单元共价偶联。根据紫外/可见光谱和循环伏安法,这些新型
吩噻嗪受体二元组在电子基态下进行电子解耦。在激发态,固有受体发光基本上被淬灭。根据 Weller 近似,从容易获得的 UV/Vis 光谱和循环伏安数据计算光致电子转移的吉布斯能量,使光激发时从
吩噻嗪到
芳烃的还原性电子转移的可行性合理化。
