Abstract

Schaltung per Temperatur: Die durch intramolekularen Protonentransfer im angeregten Zustand (ESIPT) hervorgerufene Lumineszenz eines Imidazo[1,2-a]pyridins kann durch thermische Kontrolle der Festkörperpackung zwischen Blaugrün und Gelb (siehe Bild) geschaltet werden. ESIPT ist somit ein vielversprechender Mechanismus für die Transduktion von Packungs- in Lumineszenzinformation, woraus sich ein neuartiges Konzept für den Entwurf von durchstimmbaren organischen lumineszierenden Feststoffen ableitet.
