Abstract

<p>The α-type isomer of [6,6]-phenyl-C<sub>71</sub>-butyric acid methyl ester (α-[70]PCBM) has been separated into enantiomers. The structures of (<i>R</i>)- and (<i>S</i>)-α-[70]PCBM were unambiguously identified by X-ray crystallography. Systematic investigations on photovoltaic properties of devices based on the optically active/inactive α-[70]PCBM acceptor and a conjugated polymer donor revealed that the enantiomer separations and combinations have insignificant effects on the device performances.</p>
