A flash photolysis and stopped-flow spectroscopy study of 3 ',4 '-dihydroxy-7-O-beta-D-glucopyranosyloxyflavylium chloride an anthocyanin analogue exhibiting efficient photochromic properties.

Résumé

The complete determination of all rate and equilibrium constants of the network of reversible chemical reactions involving the anthocyanin analogue, 3′,4′-dihydroxy-7-O-β-D-glucopyranosyloxyflavylium chloride, was achieved by means of UV-visible spectroscopy, flash photolysis and pH jumps monitored by stopped-flow. An energy level diagram containing all the data was obtained. A detailed step by step procedure illustrating all the calculations is reported.
