porphyrin. The porphyrin dyads were titrated with phenylimidazole appended fullerenes, N -Methyl-4-(1H-imidazol-1-yl)phenylfullero[C 60 ]pyrrolidine or N -Methyl-4-(1H-imidazol-1-yl)phenylfullero[C 70 ]pyrrolidine and supramolecular triads of the type, (PTZ or BBA) 4 -ZnP:(C 60 Im or C 70 Im) were formed in which, zinc porphyrin and fullerenes act as primary electron donor and acceptors, while phenothiazine
摘要 两种基于锌卟啉的二元组,5, 10, 15, 20-tetra-4-(2-(10H-phenothiazin-10-yl)ethoxy)苯基卟啉锌 (II) 和 5,10,15,20-tetra-合成了含有四个吩噻嗪或双(4'-叔丁基联苯基-4-基)苯胺部分的 4-(双(4'-叔丁基联苯基-4-基)氨基)苯基卟啉锌(II),这些基团连接在卟啉骨架上,并使用 1 H NMR、质量、UV-可见光和稳态荧光技术进行系统表征。5,10,15,20-四-4-(双(4'-叔丁基联苯-4-基)氨基)苯基卟啉锌(II)在335nm激发,导致双(4'-叔丁基联苯-4-基)苯胺部分,与原始双(4'-叔丁基联苯-4-基)苯胺相比,在618nm处出现卟啉发射,由于分子内能量从双(4'-叔丁基联苯-4-基)苯胺部分转移到卟啉。卟啉二元组用苯基咪唑附加的富勒烯、N-甲基-4-(1H-咪唑-1-基)苯基富勒烯[C
