合成了三种铂（II）席夫碱配合物，并以钴配合物为催化剂，在可见光照射下对混合溶剂光催化制氢进行了研究。考察了它们的物化性能和电化学性能，并在不同催化条件下评价了它们的催化活性。在优化的条件下，配合物1的转化数（TONs）达到601，并研究了配合物中不同基团对光催化活性的影响。三种PS的光催化效率与得到的MLCT激发态的猝灭速率常数吻合得很好。
Three platinum(II) Schiff base complexes were synthesized and were used as efficient photosensitizers (PSs) for the photocatalytic H2production from mixed solvents under visible light irradiation with a molecular cobalt complex as catalyst. Their photophysical and electrochemical properties were investigated and catalytic activities were evaluated under different catalytic conditions. The turnover numbers (TONs) up to 601 for complex1was achieved under optimized conditions and the effects of different groups in the complexes on the photocatalytic activity were presented. The photocatalytic efficiencies of three PSs are in good agreement with obtained quenching rate constant of the MLCT excited state.
