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.
