Article abstract of DOI:10.1016/j.jphotochem.2012.06.013

The compounds 3′-butoxy-7-methoxyflavylium and 3′-butoxy-7- hydroxyflavylium were synthesized and the respective equilibrium and rate constants determined by two complementary techniques, pH jumps and flash photolysis. An experimental strategy based on th
