基于原位转化2+1型配体的铜配位聚合物:合成、结构及催化性质

A copper complex constructed based on the ligand in situ with 2+1 coordination mode: synthesis,structure and catalytic property

本文选用含有氰基的配体3,5-di-[1,2,4]triazol-1-yl-benzonitrile (DTCN),借助水热合成的方法,与Cu^(2+)离子结合,成功地构筑了一个金属-有机配合物[Cu(DTBA)2](1)(HDTBA=3,5-di-[1,2,4]triazol-1-yl-benzoic acid),通过X-ray、IR等手段,对它的结构进行了初步的表征.结构分析表明,DTCN配体中氰基发生了原位转化,生成了羧基,并与Cu^(2+)离子形成了配位,同时,通过配体中的三氮唑的连接作用,进一步形成了具有格子状特征的2D层.另外还研究了这个配合物,对亚甲基蓝(MB)光催化降解性能.

A cyano ligand,3,5-di-[1,2,4]triazol-1-yl-benzonitrile(DTCN),was chosen to react with Cu(Ⅱ)ion under hydrothermal condition,giving a new metal-organic complex,[Cu(DTBA)2](1),which was further characterized by single crystal X-ray diffraction and IR spectra.Compound 1 has a 2D network structure,where the ligand DTCN was transformed in situ into the 3,5-di-[1,2,4]triazol-1-yl-benzoic acid(HDTBA)ligand.The catalytic property of compound 1 has also been studied.
