利用联苯四羧酸(H4bptc)和双三唑乙烷(bte)合成了2个配位聚合物{[Zn2(bptc)(DMF)2(H2O)]·DMF·H2O}n(1)和{[Zn(bte)(bptc)0.5]·DMF·0.5H2O}n(2)。化合物1为三维Pt S-拓扑结构,在该配合物中每个双核次级构筑单元(SBU){Zn2(O2CR)4}与4个联苯四酸配体相连,从而将配合物构筑成了三维MOF结构。化合物2为二维梯形结构,并通过弱氢键O…H-C将二维层连接为三维结构。同时对配合物的热稳定性和荧光特征进行了讨论。
Two coordination polymers {[Zn2 (bptc) (DMF) 2 (H2O)] · DMF · H2O} n (1) were synthesized using biphenyltetracarboxylic acid (H4bptc) and bistriazole ethane {[Zn (bte) (bptc) 0.5] · DMF · 0.5H2O} n (2). Compound 1 is a three-dimensional Pt S- topology in which each binuclear secondary building block (SBU) {Zn2 (O2CR) 4} is linked to four biphenyl tetracarboxylic acid ligands to construct a complex Three-dimensional MOF structure. Compound 2 is a two-dimensional trapezoidal structure and connects two-dimensional layers to three-dimensional structures through weak hydrogen bonds O ... H-C. The thermal stability and fluorescence characteristics of the complexes were also discussed.
