We report the synthesis, optical, electrochemical, electronic structural, and transient optical properties of conjugated (porphinato)zinc(II)-spacer-(porphinato)zinc(II) (PZn-Sp-PZn) complexes that possess intervening conjugated Sp structures having varying degrees of proquinoidal character. These supermolecular PZn-Sp-PZn compounds feature Sp moieties (4,7-diethynylbenzo[c][1,2,5]thiadiazole (E-BTD-E)
我们报告了共轭 (porphinato)zinc(II)-spacer-(porphinato)zinc(II) (PZn-Sp-PZn) 配合物的合成、光学、电化学、电子结构和瞬态光学性质,这些配合物具有中间的共轭 Sp 结构,具有不同程度的原醌型特征。这些超分子 PZn-Sp-PZn 化合物具有 Sp 部分 (4,7-二乙炔基苯并[c][1,2,5]噻二唑 (E-BTD-E)、6,13-二乙炔基并五苯 (E-PC-E)、 4,9-二乙炔基-6,7-二甲基[1,2,5]噻二唑并[3,4-g]喹喔啉(E-TDQ-E)和4,8-二乙炔基苯并[1,2-c:4, 5-c']双([1,2,5]噻二唑)(E-BBTD-E)}调节前沿轨道能级并逐渐增加对地面和电子激发态的醌共振贡献的程度,增加终端之间的电子通信量级 (5,-10, 20-二(芳基)卟吩基)锌(II)单元,相对于双[(5,5',-10
