Abstract

Nächster Halt Guanin: Der Wirkungsgrad der photoinduzierten Ladungstrennung zwischen den Donor- und Akzeptorchromophoren einer Polyadeninsequenz, die eine einzelne Guaninbase (G) enthält, hängt empfindlich von der Position von G und von der Gesamtlänge der Polypurinsequenz ab. Quantenausbeuten sprechen für einen stufenweisen Mechanismus mit G als „Haltepunkt“ im Gesamtprozess (Sa: Elektronenakzeptor Stilbendicarboxamid, Sd: Elektronendonor Stilbendiether).
