The present invention provides a metalporphyrin complex having structure represented by formula (I), wherein R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are independently selected from one of hydrogen, halogen, aliphatic group, substituted heteroaliphatic group, aryl and substituted heteroaryl; n is 1-6; L is quaternary ammonium functional group or quaternary phosphonium functional group; M is a metal element; and X is one of halogen, —NO3, BF4—, —CN, p-methyl benzoate, o-nitrophenol oxygen anion, 2,4-dinitrophenol oxygen anion, 2,4,6-trinitrophenol oxygen anion, 3,5-dichlorophenol oxygen anion and pentafluorophenol oxygen anion. The metalporphyrin complex provided in the present invention has two quaternary ammonium functional groups or two quaternary phosphonium functional groups, and compared with the prior art, the metalporphyrin complex shows higher catalytic activity in catalyzing polymerization reaction of carbon dioxide and an epoxide.
本发明提供了一种金属卟啉配合物,其结构由式(I)表示,其中 R1、R2、R3、R4、R5、R6、R7、R8、R9 和 R10 独立选自氢、卤素、脂肪族、取代的杂脂肪族、芳基和取代的杂芳基中的一种;n 为 1-6;L 是季铵官能团或季鏻官能团;M 是金属元素;X 是卤素、-NO3、BF4-、-CN、对甲基苯甲酸酯、邻硝基苯酚氧阴离子、2,4-二硝基苯酚氧阴离子、2,4,6-三硝基苯酚氧阴离子、3,5-二氯苯酚氧阴离子和五氟苯酚氧阴离子中的一种。本发明提供的金属卟啉络合物具有两个季铵官能团或两个季膦官能团,与现有技术相比,金属卟啉络合物在催化二氧化碳与环氧化物的聚合反应中表现出更高的催化活性。
