Hydrogen atom transfer of 5-hydroxyflavone in the excited triplet state
Behavior of 5-hydroxyflavone (5HF) in the excited triplet state was studied for the first time by transient absorption and phosphorescence spectroscopies. 5HF underwent the intramolecular hydrogen atom transfer in the excited triplet state at room temperature.
