A comparative study of the photophysical properties of three flavonoids (flavone (F), 7-methoxyflavone (7MF) and 3-methoxyflavone (3MF)), which may serve as models for naturally occurring flavonoids, shows a distinct behaviour of the 3-methoxy derivative. Steady state and transient spectroscopic investigations reveal an almost quantitative formation of the triplet states of F and 7MF, which can be...
