本文合成了一种配体:(2-NO_2),5,10,15,20-四(对-磺酸基苯基)卟啉九水合物((2-NO_2)TPPS·9H_2O(I)),六种金属螯合物:Zn~1(2-NO_2)TPPS·10H_2O(Ⅲ),Ru~1(CO)IPPS·9H_2O(Ⅲ),Rh~1(2-NO_2)TPPS·8H_2O(Ⅳ),Rh~1Cl(2-NO_2)TPPS·8H_2O(Ⅴ),Cd~1(2-NO_2)TPPS·12H_2O(Ⅵ)及Hg~1(2-NO_2)TPPS·9H_2O(Ⅶ)。进行了元素分析、电子光谱、IR~1HNMR和TGA研究。测试了光敏剂-K_2PtCl_5-TiCl_3体系的放氢功能。讨论了β-NO_2、轴向配体和金属离子对螯合物光敏性能的影响。
In this paper, a ligand was synthesized: (2-NO_2), 5,10,15,20-tetrakis (p-sulfophenyl) porphyrin nonahydrate (2-NO_2) TPPS · 9H_2O , Six metal chelates: Zn ~ 1 (2-NO_2) TPPS · 10H_2O (Ⅲ), Ru ~ 1 (CO) IPPS · 9H_2O , Rh ~ 1Cl (2-NO_2) TPPS · 8H_2O (Ⅴ), Cd ~ 1 (2-NO_2) TPPS · 12H_2O (Ⅵ) and Hg_1 (2-NO_2) TPPS · 9H_2O (Ⅶ). Elemental analysis, electron spectroscopy, IR ~ 1HNMR and TGA studies were performed. The hydrogen-releasing function of photosensitizer-K_2PtCl_5-TiCl_3 system was tested. The effects of β-NO 2, axial ligands and metal ions on the chelate photosensitivity were discussed.
