New C,N,S-cyclometalated palladium(II) and platinum(II) complexes have been synthesized and their structural, electrochemical, and photochemical properties examined. The blue color of these complexes in solution changed to yellow under visible-light irradiation. By measurement of the absorption spectra for quantifying changes in color, isosbestic points for each complex clearly indicated the presence
已经合成了新的C,N,S-环金属化的钯(II)和铂(II)配合物,并研究了它们的结构,电化学和光化学性质。在可见光照射下,溶液中这些配合物的蓝色变为黄色。通过测量吸收光谱以量化颜色变化,每个复合物的等吸收点清楚地表明仅存在两种负责颜色变化的物质。X射线分析表明,可见光诱导的黄色物质是S-氧化的磺胺盐配合物。通过直接检测1275 nm处的单线态氧发光,证实了光敏化的单线态氧(1O2)的产生。本发明的环金属化钯(II)和铂(II)配合物是单线态氧的有效光敏剂,
