Abstract

original image

Micellare Verkehrsampeln: Das im Titel bezeichnete System mit resonantem Fluoreszenzenergietransfer (FRET) nutzt eine Art Donorfarbstoff und zwei Arten Akzeptorfarbstoffe. Das An- und Ausschalten der Fluoreszenz der beiden Akzeptorfarbstoffe kann über den pH-Wert bzw. Licht gesteuert werden. Dieses neuartige vielfarbige lumineszierende Polymersystem kann als ratiometrische Sonde mit einstellbarer Empfindlichkeit für pH-Wert und Temperatur fungieren.
