Titania metal-organic frameworks (MOFs) are attractive materials for noble-metal-free heterogeneous photocatalysis because of their tunable photoredox activity. In this work, we present the effect of decreased pore-steric interference in photocatalysis by creating a new series of MOFs via isoreticular expansion. These new UCFMOFs pack in a hex rod net, are composed of 1-dimensional titania secondary building units and organic links of increased metrics, exhibiting pore apertures with expanded sizes and increased photocatalytic kinetics. Powder based crystallography, in tandem with local structure, gas adsorption, and DFT studies, enabled elucidation of their crystal, steric, and electronic structures that explain their increased photocatalytic efficiency towards mild oxidation of organic probes.<br>

We report here the synthesis of a robust and highly porous Fe-phenanthroline-based metal–organic framework (MOF) and its application in catalyzing challenging inter- and intramolecular C–H amination reactions. For the intermolecular amination reactions, a FeBr2-metalated MOF selectively functionalized secondary benzylic and allylic C–H bonds. The intramolecular amination reactions utilizing organic azides as the nitrene source required the reduction of the FeBr2-metalated MOF with NaBHEt3 to generate the active catalyst. For both reactions, Fe or Zr leaching was less than 0.1%, and MOFs could be recycled and reused with no loss in catalytic activity. Furthermore, MOF catalysts were significantly more active than the corresponding homogeneous analogs. This work demonstrates the great potential of MOFs in generating highly active, recyclable, and reusable earth abundant metal catalysts for challenging organic transformations.
