Abstract

Ultrafast pump−probe studies of room-temperature solutions of 3-hydroxyflavone (3-HF) and some 4‘-substituted derivatives have been undertaken. Transient absorption attributable to the two zwitterionic forms of the excited tautomer arising from excited-state intramolecular proton transfer (ESIPT) wa...
