Abstract
Two new coordination polymers, [Cd(bpdc)(bibp)(H2O)2] n (1) and [Zn(bpdc)(bibp)] n (2), have been hydrothermally synthesized from 2,2′-biphenyldicarboxylate (bpdc) and 2,2′-bis(imidazol-1-ylmethyl)-biphenyl (bipb). Polymer 1 features a 1-D tubelike porous chain along the a direction with coordinated water molecules occupying the pores. The double-chain of polymer 2 possesses alternating rectangular rings [(bpdc)2Zn2] and [(bibp)2Zn2] with Zn as nodes. The polymers exhibit strong fluorescent emissions in the solid state at room temperature and could be significant as photoactive materials.
