| 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) andCd(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. |
