二硫键金属卟啉的合成及电催化还原氧气
Preparation of Metalloporphyrin with Disulfide Bond and Electrocatalytic Reduction of Oxygen
摘要
Abstract
A novel amino acid derivatised mesoporphyrin Co (Ⅱ)-[2,7,12,18-tetramethyl-3,8-diethyl-13,17-(propionylaminoethyl-dithio-ethyaminoformylethyl)-29,34-bis-(methoxy-formyl)]-prophyrin [Co (Ⅱ)MPDTEP,Ⅴ] was prepared from hemin by a six-steps reaction including deferrization,esterification,catalytic hydrogenation,hydrolyzation,condensation and complexation.The target products were characterized.The effects of the reaction time and temperature on the yields of the product [2,7,12,18-tetramethyl-3,8-diethyl-13,17-(propionylaminoethyl-dithio-ethyaminoformylethyl)-29,34-bis-(methoxy-formyl)]-prophyrin (MPDTEP,Ⅳ) were investigated.A gold electrode modified by Co (Ⅱ)MPDTEP was prepared by self-assembly of disulfide on gold.The properties of the modified electrode were investigated by FTIR as well as electrochemical methods.This modified electrode was successfully used for the electrocatalytic reduction of oxygen.关键词
