摘要：
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) (H(2)tba =5-tert-butylisophthalic acid, H(2)ada =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.
