三苯胺类多羧酸有机配体因在光电功能材料领域表现优异而受到学者广泛地关注.本文选择一个具有纳米尺寸臂长的配体三(4′-羧基联苯基)胺(H_3TPA),在不同的反应条件下,分别与MnCl_2·4H_2O,Cu(NO_3)_2·6H_2O和Co(NO_3)_2·6H_2O反应,合成了3例结构新颖的金属有机框架(MOF)材料,[Mn(HTPA)(DMA)]_n·x G(FIR-31,DMA=N,N-二甲基乙酰胺,G=客体分子),[(Me_2NH_2)(Cu(TPA)]_n·x G(FIR-32),[(Co_3(TPA)_2(TMEA)_2]_n·x G(FIR-33,TMEA=N,N,N′-三甲基乙二胺).X射线单晶衍射结果表明,FIR-31是由双核[Mn_2(COO)_4]次级构筑单元(SBU)通过未完全脱质子的HTPA2-配体桥联形成的二维(4,4)-sql层状结构;FIR-32则是一个具有(3,6)-kgd拓扑网络的阴离子型二维层,其SBU为双核的[Cu_2(COO)_6];而FIR-33是由三核[Co_3(COO)_6]SBU构筑的具有(3,6)-kgd拓扑类型的二维层结构.
The triphenylamine-based polycarboxylic acid organic ligands have attracted a great deal of attention due to their excellent performance in the field of optoelectronic functional materials.In this paper, we selected a tris (4’-carboxybiphenyl) amine (H_3TPA) ligand with nano- Three novel MOF materials were synthesized by reaction with MnCl 2 · 4H 2 O, Cu (NO 3) 2 · 6H 2 O and Co (NO 3) 2 · 6H 2 O under different reaction conditions.
