Polyoxometalate-cucurbituril Molecular Solid as Photocatalyst for Dye Degradation under Visible Light

An organic-inorganic hybrid molecular solid based on Lindqvist-type polyoxometalate (POM) anions, {;W6O19};2 −, and decamethylcucurbit[5]uril (Me10CB[5]) was synthesized under hydrothermal condition. In the structure of {;[Na2(W6O19)(Me10CB[5])(H2O)]·2H2O};n (complex 1), the sodium cations, {;W6O19};2 − anions, and Me10CB[5] macrocycles formed a 1D chain subunit that assembled into a 3D supramolecular host-guest network through extensive supramolecular interactions. Furthermore, the complex displayed enhanced photocatalytic activity towards the degradation of rhodamine B (RhB) in water under visible light irradiation.
