Axially substituted phosphorous(v) corrole with polycyclic aromatic hydrocarbons: syntheses, X-ray structures, and photoinduced energy and electron transfer studies

Abstract

Excited state energy and electron transfer processes in naphthalene and pyrene appended phosphorous(v) corroles.

Phosphorus corrole complexes: from property tuning to applications in photocatalysis and triplet–triplet annihilation upconversion

“…7a, the ground state difference absorption spectra). These new absorption bands may safely be attributed to the radical anion of the corroles 62. Interestingly, the photo-reduction process is reversible, clearly evident by the recovery of the pink color of the corrole solution after exposure of the irradiated solution to air (Fig.…”

Tuning Chemical and Physical Properties of Phosphorus Corroles for Advanced Applications

“…These discouragingr esultsa re in contrast with the facile ligand exchange of cationic phthalocyanine/porphyrin analogsa nd the electron-rich triphenylcorrole complex (P-TPC-(OH) 2 ), [4a, 12e] but similar to other electron-deficient phosphorus corroles. [14] The reason is that the equilibrium described in Scheme 1i si nf avor of the substitution-inert six-coordinate trans-dihydroxo rather than the five-coordinate species. Indeed, removal of one hydroxyl group in P-OH by trifluoroacetic acid (TFA) required5 000 equiv.…”

A Six Coordinated Phosphorus(V) Corrole Bearing Two Hydroxyl Axial Ligands: X‐Ray Structure, DNA Interaction, Photonuclease Activity, and Cytotoxicity towards Tumor Cells

“…The first synthesis of phosphorus corrole may trace back to 1998, in which free base corrole reacts with POCl 3 in pyridine solvent and yields the P(V) corrole bearing one hydroxyl axial ligand as confirmed by X‐ray crystallography [10] . The axial hydroxyl group may be replaced by methoxy group, [11] porphyrin phenyl hydroxyl group, [12] silyloxy group, [13] or hydroxyl group of polycyclic aromatic hydrocarbon [14] . When PCl 3 was used as phosphorus reagent, P(V) corrole bearing oxo axial ligand might be obtained [15] .…”
