通过各种偶合反应(如Mizoroki-Heck反应,烯烃复分解和Sonogashira偶合)合成的光官能多核配合物的桥联配体中的乙烯基或乙炔基连接体已通过光化学加氢成功转化为相应的饱和碳链,并在的MeCN-吡啶-CF 3 COOH(3:1:0.1 v / v / v)的混合的含起始金属配合物和1,3-二甲基-2-苯基-2,3-二氢-1-溶液ħ -苯并[ d ]咪唑(BIH)作为可见光照射下的牺牲电子供体,产率很高。Ru 2 -Re三核络合物中连接基的加氢提高了CO 2还原的光催化能力。
Various photofunctional metal complexes with functional groups, i.e. bromo and vinyl groups, were integrated into hetero-multinuclear complexesusing the Mizoroki–Heck reaction. The obtained trinuclear complexes absorb a wide range of visible light and have a long excited state lifetime and the photocatalytic ability to obtain CO2 reduction.
