Abstract

original image

Ein Through-Space-Superaustausch scheint für die Ladungsrekombination (CR) nach Photoanregung und Ladungstrennung (CS) in Zinkporphyrin-C60-Rotaxanen maßgeblich zu sein (siehe Bild). Darauf weist die niedrige Aktivierungsenergie dieses Prozesses hin, an dem außerdem ein relativ langlebiger Ladungstrennungszustand beteiligt ist.
