摘要
This paper deals With some of the mh activities in our group in recent years in the areas of artificial enzyme models with porphyrin, steroids and calixarenes as building units. Wherein two kinds of novel enzym models of steroids-metalloporphyrin and calixarene-metalloporphyrin have been synthesized and employed as cytochrome P450 modeling. These biomimetic systems exhibited high catalytic selectivity and efficiency in oxidation of olefins (styrene, cyclohexene) and hydrocarbonds (isopropylbenzene) as well as phenol (p-benzenediol). The excellent catalytic property stems mainly from hydrophobic effect and multiple recognition sites that lead to cooperative catalysis.
