Anion Effect on the Excited-State Intramolecular Proton Transfer of 4′-N,N-Diethylamino-3-hydroxyflavone in Ionic Liquids

The excited-state intramolecular proton transfer (ESIPT) reaction of 4′-N,N,-diethylamino-3-hydroxyflavone (C2HF) was studied using time-resolved fluorescence measurements in ionic liquids (ILs) of various anions with a fixed cation (1-ethyl-3-methylimidazolium [C2mim]+). C2HF showed an ESIPT reacti...
