La bioluminescence est un phénomène naturel au cours duquel des organismes vivants convertissent de l’énergie chimique en lumière. Dans le cas de la luciole, la réaction implique une réaction d’oxydation de la luciférine, catalysée par la luciférase, produisant le photoproduit oxyluciférine dans son premier état excité. L’oxyluciférine peut ensuite émettre une lumière pouvant varier du jaune-vert au rouge par relaxation vers son état fondamental. Le photoproduit peut exister sous six formes chimiques différentes provenant d’une conversion kéto/enol et de déprotonations des groupes phénols ou énols. La première partie de la thèse consistera à étudier les propriétés optiques des différentes formes chimiques en solution aqueuse, ainsi qu’à rés...
