Abstract

A series of azahomofullerenes and poly(amino)fullerenes were synthesized. Photoluminescence (PL) and photovoltaic (PV) measurements were performed on the composite films of conjugated polymer MEH‐PPV with fullerene derivatives to investigate the influence of an electron acceptor on the charge‐transfer process between components of PV system. We found that the PL of MEH‐PPV is strongly quenched by the admixture of the fullerene derivative. The efficiency in the PV device containing the blend MEH‐PPV/azahomofullerene is two orders of magnitude higher than in pure MEH‐PPV.
