Abstract
Two different processes, namely the Bamford–Stevens and [4 + 2] Diels Alder reactions, have beenoptimized under microwave irradiation for the functionalization of fullerenes. In this manner, all the mainC60- and C70-based acceptor derivatives for organic solar cells such as PCBM, DPM, BHN and ICBA,have been prepared in higher yields and shorter reaction times with respect to the reported data. Thesefindings represent a step forward toward the wide production of cheaper organic solar cells as aconsequence of the cost abatement of the acceptors given by higher yields, lower waste production,and reduced reaction time which means a strong energy saving.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
