摘要
通过脲热合成法合成了2个金属配位聚合物[Mn3(Hidc)3(DMI)2]n(1)(H3idc=4,5-咪唑二羧酸,DMI=1,3-二甲基-2-咪唑啉酮),[Co(tbip)(DMPU)]n(2)(H2tbip=5-叔丁基间苯二甲酸,DMPU=N,N-二甲基丙烯基脲)。通过元素分析、红外光谱、X射线粉末衍射、单晶X射线衍射等对配合物进行了结构表征。结果表明:配合物1属单斜晶系,空间群为P21/n。该配合物以DMI为模板剂,通过H3idc与Mn(Ⅱ)构筑成三维四方孔道结构,DMI填充在孔道中。配合物2属单斜晶系,空间群为P21/c。该配合物以DMPU为模板剂,通过H_2tbip与Co(Ⅱ)构筑成二维网状结构,DMPU分子通过与Co(Ⅱ)配位填充在网格中。固体荧光性能测试表明配合物1在462 nm处存在较强的荧光发射峰,说明具有良好的蓝光性质。
Two new metal complexes,[Mn3(Hidc)3(DMI)2]n(1)(H3idc=4,5-imidazoledicarboxylic acid,DMI=1,3-dimethyl-2-imidazolidinone)and[Co(tbip)(DMPU)]n(2)(H2tbip=5-tert-butylisophthalic acid,DMPU=N,N-dime-thylpropyleneurea),have been synthesized by urothermal method.The single crystal X-ray diffraction analysis shows that complex 1 exhibits a three-dimensional structure with square-shaped pores constructed by H3idc and Mn(Ⅱ),and DMI molecules are filled in the pores.Complex 2 is a two-dimensional network structure constructed by H2tbip and Co(Ⅱ)using DMPU as a template,and DMPU molecules are filled in the grids of network by coordinating with Co(Ⅱ).Solid fluorescence measurement reveals that complex 1 possesses blue fluorescence property with a strong emission at 462 nm.
