Dual-ligand approach to the synthesis of new luminescent cadmium(II) coordination polymers with one- and two-dimensional homochiral structures

Two new homochiral cadmium(II) coordination polymers, Cd2(bipy)2(H2O)2 (cam)2 (1) and Cd2(phen)2(cam)2·eg (2), where bipy = 2,2′-bipyridine, phen = 1,10-phenanthroline, H2cam = (1R, 3S)-(+)-camphoric acid, and eg = ethylene glycol, have been synthesized by a dual-ligand approach. Compound 1 possesses a chain-like architecture and compound 2 has a layered structure with a (4,4) grid topology. Both compounds crystallize in the space group C2 and exhibit intense photoluminescence upon photoexcitation at 280 and 300 nm, respectively.

Graphical abstractTwo homochiral cadmium(II) coordination polymers with one- and two-dimensional frameworks have been synthesized by a dual-ligand approach. The thermal stabilities and photoluminescent properties of the two compounds have been described along with their crystal structures.Figure optionsDownload full-size imageDownload as PowerPoint slide
