Chiral coordination polymer as a luminescence sensor for small organic molecules

The new coordination polymer {[Cd₂(bptc)(H₂O)₆]·2H₂O}_n, where H₄bptc is 3,3′,5,5′-biphenyltetracarboxylate, has been synthesized hydrothermally and characterized. In this complex, bptc⁴⁻ as tridentate ligands connect the Cd²⁺ cations to form a chiral 2D layer, which crystallizes in the ortho-rhombic chiral space group C222. The compound exhibits the properties of luminescence sensor for organic molecules.
