本文综述了近二十年来作者组在多吡啶钌（II）光敏剂和铂（II）基分子催化剂组成的光放氢分子器件（PHEMD）方面的研究进展。首先介绍了各种实验证据所证明的Pt（II）基分子催化剂的放氢活性。然后详细讨论了Ru（II）Pt（II）基PHEMDs的构效关系、提高催化活性所需的一些重要因素以及对光化学放氢机理的一些重要认识。
This article summarizes the ongoing studies on the photo-hydrogen-evolving molecular devices (PHEMDs) made up of polypyridyl Ru(II) photosensitizers and Pt(II)-based molecular catalysts, carried out in the authors' group in the last two decades. The H-2-evolving activities of Pt(II)-based molecular catalysts demonstrated by various experimental evidences are first described. Then the structure-activity relationship, some important factors required for the higher catalytic activity, and several important insights into the mechanism of photochemical H-2 evolution catalyzed by the Ru(II) Pt(II)-based PHEMDs will be discussed in detail.
