本文以刚性间苯二酸(IP),对苯二酸(TP)及柔性丁二酸(SU)为桥联配体,溶剂热法合成了3个配合物[CdCrP)(DPQ)(H2O)k(1),[Cd(IP)(DPPZ)]n(2)和[Cd(su)(DPPZ)]。(3)(DPQ:毗嗪(2,3-f][1,10]菲咯啉,DPPZ=二毗啶[3,2-a:2′,3′-c]并吩嗪)。通过x射线单晶衍射分别测定了它们的结构。3个配合物均为单斜晶系,空间群分别为P21/c(配合物1和3)和c2/c(配合物2)。配合物荧光性质的表征表明,采用刚性二酸有利于配位聚合物荧光的增强。
Three cadmium(H) dicarboxylate coordination polymers have been synthesized by solvothermal method: [Cd(TP)(DPQ)(H2O)], (1), [Cd(IP)(DPPZ)]n (2) and [Cd(SU)(DPPZ)]n (3) (TP=terephthalate, IP=isophthalate, SU= succinate, DPQ=pyrazino[2,3-f][1,10]phenanthroline, DPPZ=dipyrido[3,2-a:2′,3′-c]phenzine). Among them, 1 and 3 crystallize in the monoclinic space group P21/c, while 2 in C2/c. Luminescent studies show that, with the flexible dicarboxylate, the fluorescence intensity of 3 is much less than that of 1 and 2. CCDC: 725669, 1; 725667, 2; 725668, 3.
