在水中采用蒸发溶剂的方法,合成了两个异质同构的单核配合物[M(phen)2(H2O)2]·2SIPH2·2H2O (M=Zn,Co),SIPH2=间苯二甲酸-5-磺酸根阴离子,phen=1,10-邻菲罗啉).在两个配合物结构单元中,中心离子与两个1,10-邻菲罗啉和两个水分子配位,形成[M(phen)2(H2O)2]2+阳离子.两个未配位的水分子与[M(phen)2(H2O)2]2+阳离子,SIPH2-阴离子通过氢键相互连接形成三维的网状结构.SIPH2-阴离子起到平衡电荷的作用.室温下两个配合物均具有荧光发射峰,其发射峰分别在460 nm和439 nm.与配体相比,均发生明显的红移.荧光寿命分别为1.7638 ms和1.6356 ms.
