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

A water-stable homochiral luminescent metal-organic framework (HLMOF), {[Cd(l)(4,4-bipy)]DMA5H(2)O}(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.
