Abstract

original image

Die nichtkovalente Selbstorganisation von Chromophoren in einem Organoton-Templat ergibt fluoreszierende Ton-Farbstoff-Hydrogele und -Filme, die als supramolekulare Lichtsammelsysteme wirken. Das Aminoton(AC)-Templat erzwingt die räumliche Orientierung der Donor- und Akzeptormoleküle und vermittelt so den resonanten Fluoreszenzenergietransfer (siehe Bild; CS=Coronensalz, PS=Perylensalz).
