为筛选光解水产氢的光敏剂, 用改进的方法, 分别合成了Rh4(CO)12和meso-四(对苯磺酸钠)卟啉(TPPS), 并在N,N-二甲基甲酰胺(DMF)中反应, 得到组成为Rh(DMF)TPPS.5H2O的新配合物, 用元素分析, 红外, 拉曼光谱, 质子核磁共振, 电子顺磁共振及热重分析, 确定了配合物的结构和Rh的价态, 并进行了Rh(DMF)TPPS-TiCl3-K2PtCl6三组份复合体系的放氢实验, 结果表明铑体系较诸钌体系有更高的放氢效率.

Rh(DMF)TPPS.5H2O [TPPSH2 = meso-tetra(sodium p-sulfonatophenyl)porphyrin] was prepared and characterized by elemental anal., IR, 1H NMR, ESR and TGA. The coordination geometry and valence state of the formed complex are discussed. The photoredn. of water by homogeneous 3-component system consisting of Rh(DMF)TPPS.5H2O, TiCl3 and K2PtCl6 was studied.
