Mixed donor, phenanthroline photoactive MOFs with favourable CO₂ selectivity

Mixed donor phenanthroline-carboxylate linkers were combined with Mn^II or Zn^II to form photoactive MOFs with large pore apertures. The MOFs display high CO₂ adsorption capacities, which consequently causes structural framework flexibility, and align with favorable metrics for selective CO₂ capture. The photophysical properties of the MOFs were investigated, with the Mn^II MOF giving rise to short triplet LMCT lifetimes.
