A functional tin(IV)-porphyrin derivative was used as a building block to construct a novel 3D porous metal-organic framework (MOF). The MOF is built up from tin(IV)-porphjrin struts linking up Zn atoms and formates joining Sn-IV centers. The immobilization of the photoactive Sn-porphyrins in the channel walls lets the MOF present remarkable photocatalytic activities for the oxygenation of phenol and sulfides, resulting in excellent yields and remarkable selectivity in heterogeneous phases.
