Homochiral porous coordination polymer of Eu for metal ion sensing and enantioselective adsorption

A novel three-dimensional homochiral porous coordination polymer was obtained by combining the luminescent component Eu( iii ) with an enantiomerically pure semirigid triangular organic ligand derived from ( l )-α-leucine. Remarkably, it not only exhibited photoluminescence and fluorescence-based metal ion sensing properties, but also displayed enantioselective adsorption of ( R )-and ( S )-1-phenylethanamine and ( R ) and ( S )-1-phenylethanol. A novel multifunctional homochiral porous metal-organic framework was obtained by combining the luminescent component Eu( iii ) with an enantiopure triangular polycarboxylic ligand.
