Photo-controlled Electrochemical Switch Based on Photochromic Tetraazaporphyrin Containing Ferrocene Units

摘要

A new photochromic compound of tetraazaporphyrin mag-nesium(II) appended with eight ferrocene units by ethynyl TPF was synthesized.Its photochromic properties and electrochemical properties were studied.As its redox potential was reversibly changed accompanying the open- and closed-ring photoisomerization of TPF with UV-vis light irradiation,TPF may be used as electrochemical switch controlled by light.
