钴卟啉配合物（（TPPCoX）-X-III）（TPP = 5，10，15，20-四苯基卟啉; X =卤化物）与离子有机铵盐组合用于环氧丙烷和二氧化碳的区域特异性共聚。反应5 h后，转化率达到188 h（-1），副产物碳酸亚丙酯控制在1%以下，所得聚碳酸亚丙酯（PPC）的数均分子量（Mn）为48 kg/mol，头尾含量为93%，碳酸酯键含量大于99%。
Cobalt porphyrin complex ((TPPCoX)-X-III) (TPP = 5, 10, 15, 20-Tetraphenylporphyrin; X = halide) in combination with ionic organic ammonium salt was used for the regio-specific copolymerization of propylene oxide and carbon dioxide. A turnover frequency of 188 h(-1) was achieved after 5 h, and the byproduct propylene carbonate was successfully controlled to below 1%, where the obtained poly(propylene carbonate) (PPC) showed number average molecular weight (M-n) of 48 kg/mol, head-to-tail content of 93%, and carbonate linkage of over 99%.
