Photochromism of the synthetic 4',7-dihydroxyflavylium chloride

The synthetic compound 4',7-dihydroxyflavylium chloride shows an interesting photochronic effect at moderately acidic pHvalues. Pale yellow solutions of this compound, equilibrated in the dark atpH3.4, become bright yellow upon irradiation with 313-nm light. Switching off the light, gives back...
