- Abstract
Metal–organic frameworks (MOFs) with negatively charged frameworks are suitable for selectively encapsulating cationic guest ions via a cation‐exchange process. Encapsulating photoactive [RuL3]2+ polypyridine complexes into the preorganized mesoscale channels of a MOF is a good method for stabilizing the excited states of the complexes. Three new RuL3@InBTB MOFs were prepared by encapsulating cationic [Ru(bpy)3]2+ (bpy=2,2′‐bipyridine), [Ru(phen)3]2+ (phen=1,10‐phenanthroline), and [Ru(bpz)3]2+ (bpz=2,2′‐bipyrazine) into the mesopores of a three‐dimensional (3D) InBTB MOF (H3BTB=1,3,5‐benzenetribenzoic acid). The photophysical properties of the resulting materials were investigated by photoluminescence (PL) analysis. The photoredox catalytic activities were also investigated for the aza‐Henry reaction, hydrogenation of dimethyl maleate, and decomposition of methyl orange under visible light irradiation at room temperature. RuL3@InBTB MOFs were found to be very stable and highly recyclable photoredox catalytic systems.
