Patent number: 10005806
Abstract: 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.
