Metalloporphyrin-Based Metal–Organic Framework Nanorods for Peroxidase-Like Catalysis

, 2022
Metal–organic frameworks (MOFs) and their derivatives are emerging biosensing platforms due to their rational structural optimization. Herein, several metalloporphyrin–Porous Coordinated Network-222 (M-PCN-222) are developed for composition-dependent ...

A greener tetraphenylporphyrin synthesis and metallation: an undergraduate teaching experiment

Green Chemistry Letters and Reviews, 2023
While porphyrin-related syntheses have become classic experiments in the undergraduate curriculum, traditional syntheses of the free-base meso-tetraphenylporphyrin (H2TPP) and its metallated derivatives can be energy-intensive, use hazardous solvents ...

Constitution and conductivity of metalloporphyrin tapes [PDF]

, 2020
Metalloporphyrin tapes form in a solvent-free oxidative chemical vapor deposition process on glass substrates. The metal center (M = NiII, CuII, ZnII, CoII, PdII, FeIIICl, 2H) in the 5,15-disubstituted porphyrin monomer affects the initial C–C coupling ...
