Abstract

In the present work we describe the synthesis and study of a Ru-Fe chromophore-catalyst assembly designed to perform the light-induced activation of an iron bound water molecule and subsequent photo-driven oxidation of a substrate. Using a series of spectroscopic techniques, we demonstrate that excitation of the chromophore unit with 450 nm light, in the presence of a sacrificial electron acceptor, triggers a cascade of electron transfers leading to the formation of a high valent iron(iv)-oxo center from an iron(ii)-bound water molecule. The activity of this catalytic center is illustrated by the oxidation of triphenyl phosphine.

摘要

在本工作中，我们描述了一种钌 - 铁发色团 - 催化剂组件的合成与研究，该组件旨在实现铁结合水分子的光致活化以及随后底物的光驱动氧化。通过一系列光谱技术，我们证明在牺牲电子受体存在的情况下，用450 nm光激发发色团单元会引发一系列电子转移，从而从铁（II）结合的水分子形成高价铁（IV） - 氧中心。三苯基膦的氧化说明了该催化中心的活性。
