| Two Helical Cadmium Coordination Polymers Based on Semi-rigid Bis(methylbenzimidazole) Ligand | |
| 摘要: 以1，4-双（2-甲基苯并咪唑-1-亚甲基）苯（bmb）为主配体与Cd（NO3）2反应，通过改变辅助双羧酸配体2个羧基间的连接基团，得到了2个配位聚合物{[Cd（bmb）（tba）]·DMF}n（1）和[Cd（bmb）（ada）]n（2）（H2tda=5-叔丁基间苯二甲酸，H2ada=1，3-金刚烷二乙酸）。结构分析表明聚合物1显示二维三明治结构，带有交替的左手和右手螺旋链。聚合物2也显示了二维三明治结构，带有meso-螺旋和微孔。聚合物1和2都显示了强的荧光发射和高的热稳定性。 | |

| Abstract: By varying the spacers between two carboxyl of dicarboxylic acid co-ligands, the reaction between ligand bmb ((bmb=1,4-bis(2-methylbenzimidazol-1-ylmethyl) benzene) and Cd(NO3)2 gave two coordination polymers, {[Cd(bmb)(tba)]·DMF}n (1) and[Cd(bmb)(ada)]n (2) (H2tba=5-tert-butylisophthalic acid, H2ada=1,3-adamantanediacetic acid). Structural analyses reveal that polymer 1 shows a 2D sandwiche structure with alternate left-and right-handed helices. Polymer 2 also exhibits a 2D sandwiche structure but with meso-helix and micropore. In addition, polymers 1 and 2 show intense fluorescence emissions and high thermostability. | |
