Electron-donating properties of p-phenylene phosphine imides: An electrochemical and spectroscopic investigation
Date of Original Version
(matrix presented) Electronic properties of phosphine imide based organic electron donors have been investigated. N,N′-p-Phenylenebis(triphenyl)phosphine imide (Ph3P=NC6H4N=PPh3, 1) has two reversible single-electron oxidations (0.04 and 0.53 V vs SCE). Spectroscopic investigations of poly-(p-phenylene phosphine imide)s (2) are similar to those of polymer model compounds, suggesting formation of localized radical cations on the polymer chains and electronically insulating phosphorus atoms.
