摘要
采用水热方法,用醚氧桥联四羧酸配体(H4L)和菲咯啉(phen)、2,2′-联吡啶(2,2′-bipy)与CdCl2·H2O反应,合成了2个一维配位聚合物[Cd2(μ5-L)(phen)2]n(1)和{[Cd2(μ4-L)(2,2′-bipy)2(H2O)2]·2H2O}n(2),并对其结构和荧光性质进行了研究。结构分析结果表明2个配合物分别属于单斜和三斜晶系,P21/c和P1空间群。聚合物1和2分别具有基于四核Cd4和Cd2单元的一维链结构。研究表明,配合物1和2在室温下能发出蓝色荧光。
Two 1 D cadmium(Ⅱ)coordination polymers,namely[Cd2(μ5-L)(phen)2]n(1)and{[Cd2(μ4-L)(2,2′-bipy)2(H2 O)2]·2 H2 O}n(2),have been constructed hydrothermally using H4 L(H4 L=2,3,3′,4′-diphenyl ether tetracarboxylic acid),phen(phen=1,10-phenanthroline),2,2′-bipy(2,2′-bipy=2,2′-bipyridine),andcadmiumchloride.Single-crystal X-ray diffraction analyses reveal that two polymers crystallize in the monoclinic or triclinic systems,space groups P21/c or P1.Polymers1 and2 show 1 D chains composed of Cd4 or Cd2 units.The luminescent properties for two compounds were also investigated.CCDC:1971327,1;1971328,2.
