Abstract

Efficient charge transfer between a newly synthesizedlow band gap (LBG) conjugated polymer and the C60 derivativePCBM is demonstrated. Spectral and time-resolved photoluminescence(PL) measurements show strong quenching and charge separation inthe picosecond time range. The charge transfer is furtherconfirmed by light-induced electron paramagnetic resonance (EPR)measurements of both the positive polarons and the fullereneradicals, which can be resolved in high-frequency EPR. Thepotential for the LBG polymer to act as acceptor was examined inblends with the para-phenylene-vinylene polymer MDMO-PPV. Nocharge transfer, but instead energy transfer from MDMO-PPV to LBGoccurs in these blends, as shown by PL spectroscopy.
