Abstract

Sensibilisierte Nah-Infrarot-Lumineszenz (NIR-Lum.) wurde bei Lanthanoiden (Ln) erstmals beobachtet (siehe Schema; Exc.=Anregung). Ermöglicht wurde dies durch Energietransfer (ET) von Ferrocen- oder Tris(bipyridin)ruthenium-funktionalisierten lichtsammelnden Einheiten. Dank der Luminszenz des Triplettzustands des Ru-Donors ließ sich der Sensibilisierungsvorgang detailliert untersuchen.
