摘要：

Three platinum(II) Schiff base complexes were synthesized and were used as efficient photosensitizers (PSs) for the photocatalytic H-2 production 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 complex 1 was 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. (C) 2013 Elsevier B.V. All rights reserved.
