Photochemical and thermal interconversions between 2-hydroxychalcones (λmax 330-360 nm) and flavylium ions (400-460 nm) have been studied in dilute aqueous ethanol solutions.The reactions were fairly clean and recyclizable, though varied with substituents and pH.The quantum yields for photochemical coloration were about 0.1 or less.
