A homochiral luminescent 2D porous coordination polymer with collagen-type triple helices showing selective guest inclusion

Abstract

A homochiral luminescent porous coordination polymer, [Cd(L)(H 2O)]̇3H 2O, with interconnected collagen like triple-helical chains has been synthesized solvothermally by using cadmium(II) salt and a newly designed d-isosorbide-based, enantiomerically pure chiral ligand. The framework is a 2D porous material and forms a 1D channel along the a axis, with the channel dimensions ∼6.2 × 4.4 Å 2. The compound has high selectivity in the uptake of water and methanol over other solvents (e.g., tetrahydrofuran, ethanol, benzene, and cyclohexane) inside the channels. © 2012 American Chemical Society.
