摘要

Protons from water are reduced by a catalytic system composed of a heteroleptic iridium(III)photosen-sitizer [Ir(ppy)2(bpy)]~+,platinum catalyst,and sacrificial reductant.The hydrogen quantum yield reaches 0.26 in this study,which proceeds via reductive quenching of the excited photosensitiz-er by triethanolamine.This simplified approach allows the characterization of degradation products that are otherwise obscured in more complex systems.A novel 16-well setup for parallel kinetic analysis of H2 evolution enables high-throughput screening of reaction conditions and quantization of the decaying reaction rate.DFT calculations rationalize the differences between this and previous studies on tris-diimine ruthenium(II)photosensitizers.
