| 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H2tbip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。 |

| Abstract: 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. |
