The preparation of a new zinc(II) metalloporphyrin, substituted with four alkylated carbazole moieties, by reaction of pyrrole and 3-formyl-9-hexylcarbazole is reported. The substitution pattern negatively shifts the redox potentials of the macrocycle and leads to a material that emits green light at 615 nm when photo-excited at 554 nm.

锌 (II) 内消旋四 (9-己基) 咔唑基卟啉的合成和表征：一种用于电致发光和光电导应用的绿色空穴传输材料

报道了通过吡咯和 3-甲酰基-9-己基咔唑反应制备一种新的锌 (II) 金属卟啉，被四个烷基化咔唑部分取代。取代模式使大环的氧化还原电位负移，并导致材料在 554 nm 光激发时发出 615 nm 的绿光。
