(Diagram presented) A phosphorus-containing hybrid porphyrin was successfully prepared via the BF3-promoted dehydrative condensation between σ4-phosphatripyrrane and 2,5-bis[hydroxy(phenyl)methyl] thiophene. The NMR and UV-vis absorption spectra, electrochemical measurements, and DFT calculations revealed that the σ3-P,N 2,S-hybrid porphyrin exhibits high aromaticity as an 18π-electron system in terms of both geometric and magnetic criteria.
