Abstract

original image

On p. 2711 J. C. G. Esteves da Silva et al. examine why the fluorescence of firefly oxyluciferin in aqueous solution is pH-sensitive, even though there is only one emitting species: the enolate anion. The pH-sensitive fluorescence is explained by the formation of enolate stacking complexes, which adopt different conformations with different pH values, thus leading to the emission of different wavelenghts.
