摘 要:合成了铁(Ⅲ)卟啉丙烯酸酯-苯乙烯共聚物并以UV-V IS,IR,ICP和相对分子质量测定进行了表征。研究了共聚物模拟细胞色素P450催化环己烷羟化作用,发现该共聚物具有比未以高分子负载的铁(Ⅲ)卟啉高很多的催化活性,循环使用多次后其催化活性基本不变,以铁(Ⅲ)卟啉周围微环境的观点讨论了实验结果。A new iron( Ⅲ ) porphrin acylate-styrene copolymer, P[ (PorFe)A-S ], was synthesized by the reaction of iron (Ⅲ) porphrin acylate with styrene and characterized by UV-Vis, IR, ICP and molecular weight determination. Its catalytic activity in hydroxylation of cyclohexane for model cytochrome P450 in the P[ (PorFe)A- S]-O2-ascrobate-thiosalicylic acid system has been studied. It was found that the P[ (PorFe)A-S] has a higher catalytic activity than non-supported iron (Ⅲ) porphyrin and its high catalytic activity remained in reuse. The catalytic activity of P[ (PorFe)A-S ] was discussed in the view of the microenvironment of iron( Ⅲ ) porphyrin. It is proposed that the catalytic activity of the P[ (PorFe)A-S] may be further enhanced by construction of a homophase catalytic system containing the iron( Ⅲ ) porphyrin acylate-styrene copolymer.
