Padua Research Archive, l’archivio istituzionale della produzione scientifica dell’Università degli Studi di Padova, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ateneo. Padua Research Archive utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishFulleropyrrolidine derivatives containing a TEMPO group (FPNOs) are examined in toluene solution, between 200 and 270 K, by TR-EPR spectroscopy afler LASER excitation. Signals of the ground and exeited states are observed and their time profiles are recorded. In presente of ferrocene the time pattern of the pola¡ is modified, showing the occurrence of intermoleeular electron transfer from the donor ferrocene to the excited FPNOs. The rate constant k~r is obtained from the simulation of the EPR signal time evolution of the ground and excited states.
