Two novel hybrid materials assembled from transition metal mono-substituted Keggin polyoxoanions with an antenna molecule were obtained and exhibit photocatalytic activity under visible light.
Two 2D isostructural organic–inorganic hybrid solid materials based on transition metal mono-substituted Keggin polyoxotungstate with an antenna molecule were synthesized under hydrothermal conditions. Compound 2 with the substituted Co( ii) exhibits good photocatalytic activity in the degradation of rhodamine-B (RB) under visible light irradiation.
