Ultrafast proton coupled electron transfer (PCET) dynamics in 9-anthranol-aliphatic amine system

Abstract

Femtosecond infrared absorption studies strongly suggest that photoexcited 9-anthranol takes part in an ultrafast electron transfer (ET) reaction in electron-donating triethylamine solvent, but that ultrafast proton coupled electron transfer (PCET) occurs in diethylamine solvent.
