Encapsulation of flavin mononucleotide (FMN) in a porphyrinatomanganese(III)-based cubic cage allowed the fast reduction of manganese(III) porphyrin in the presence of nicotinamide adenine dinucleotide (NADH). This supramolecular system was capable of efficiently activating dioxygen and catalyzing the oxidation of benzyl alcohol. Control experiments suggested that the close proximity between FMN and manganese(III) porphyrins forced by the host-guest interaction might benefit the electron-transfer process from the FMN cofactor to the metal centers.

A series of (metallo)porphyrin imine gels have been synthesized based on imine chemistry. The resulting aerogels have sponge-like porous networked structures consisting of interconnected nanoparticles with hierarchical porosity. The aerogels have high specific surface areas (up to 719 m2 g-1) and large pore volumes (up to 2.60 cm3 g-1). The effect of metal ions on the uptake of gases in these aerogels was investigated. The impregnation of various metal ions (Pd(ii), Ni(ii), Mn(iii), Fe(iii) and Sn(iv)) enhances the uptake capacity of various gases (e.g., CO2) despite their higher densities. Among the metal ions, Pd(ii) is the best to increase the adsorption capacity and the isosteric heat of CO2 adsorption. The Pd-tapp-A4 aerogel exhibits CO2 volumetric uptake (1.62 mmol g-1, 7.13 wt% at 298 K, 1 bar) with a high isosteric heat of adsorption (40.0 kJ mol-1). The gels also show potential applications in catalysis because of their unique hierarchical porosity and the availability of metal centers. In combination with microfluidic technology, a catalytic gel capillary reactor has been assembled with the Pd-tapp-A4 gel supported on the inner surface of a functionalized capillary.
