Metal-organic layers (MOLs) have recently emerged as a novel class of molecular 2D materials with significant potential for catalytic applications. Herein we report the design of a new multifunctional MOL, Hf12-Ir-Ni, by laterally linking Hf12 secondary building units (SBUs) with photosensitizing Ir(DBB)[dF(CF3)ppy]2+ [DBB-Ir-F, DBB = 4,4'-di(4-benzoato)-2,2'-bipyridine; dF(CF3)ppy = 2-(2,4-difluo
金属有机层 (MOL) 最近已成为一类具有催化应用潜力的新型分子 2D 材料。在此,我们报告了一种新型多功能 MOL Hf12-Ir-Ni 的设计,通过将 Hf12 二级构建单元 (SBU) 与光敏 Ir(DBB)[dF(CF3)ppy]2+ [DBB-Ir-F, DBB] 横向连接= 4,4'-di(4-benzoato)-2,2'-联吡啶;dF(CF3)ppy = 2-(2,4-difluorophenyl)-5-(trifluoromethyl)pyridine] 桥接配体并用催化 Ni(MBA)Cl2 [MBA = 2-(4'-methyl-[2]) 垂直终止 SBU ,2'-联吡啶]-4-基)乙酸酯]封端剂。Hf12-Ir-Ni 采用自下而上的方法合成,并通过多种技术进行表征,包括 TEM、AFM、PXRD、TGA、NMR、ICP-MS、UV-Vis 和发光光谱。光敏 Ir 中心和催化
