3-Hydroxyflavone
Encyclopedia
3-Hydroxyflavone is a chemical compound. It is the backbone of all flavonols, a type of flavonoid
. It is a synthetic compound, which is not found naturally in plants. It serves as a model molecule
as it possesses an excited-state intramolecular proton transfer (ESIPT) effect to serve as a fluorescent probe to study membranes for example or intermembrane proteins. The green tautomer emission (λmax ≈ 524 nm) and blue-violet normal emission (λmax ≈ 400 nm) originate from two different ground state populations of 3HF molecules. The phenomenon also exists in natural flavonols.
is a chemical reaction whereby a chalcone undergoes an oxidative cyclization to form a flavonol.
