Supercritical CO₂ Synthesis of Porous Metalloporphyrin Frameworks: Application in Photodynamic Therapy.

ABSTRACT: A series of porous metalloporphyrin frameworks prepared from the 5,10,15,20-tetra(4-pyridyl)porphyrin (H₂TPyP) linker and four metal complexes, M(hfac)₂ M = Cu(II), Zn(II), Co(II), and Ni(II) (hfac: 1,1,1,5,5,5-hexafluoroacetylacetonate), were obtained using supercritical CO₂ (scCO₂) as a solvent. All the materials, named generically as [M-TPyP] _n , formed porous metal-organic frameworks (MOFs), with surface areas of ∼450 m² g^-1. All MOFs were formed through the coordination of the metal to the exocyclic pyridine moieties in the porphyrin linker. For Cu(II), Zn(II), and Co(II), incomplete metal coordination of the inner pyrrole ring throughout the structure was observed, giving place to MOFs with substituti
