A water-stable homochiral luminescent MOF constructed from an achiral acylamide-containing dicarboxylate ligand for enantioselective sensing of penicillamine

Abstract

A water-stable homochiral luminescent metal–organic framework (HLMOF), {[Cd(L)(4,4′-bipy)]·DMA·5H₂O}_n (1), was obtained by a spontaneous symmetry-breaking crystallization from achiral precursors without any enantiopure auxiliary. The homochirality of 1 was confirmed by single-crystal X-ray diffraction and CD spectroscopy. Complex 1 exhibits an interesting enantioselective sensing of D/L-penicillamine in water.
