High-molecular weight anthracene containing PPE-PPV copolymers with linear and/or branched alkyl side chains have been synthesized and investigated in polymer–fullerene bulk heterojunction solar cells. In their paper on pp. 2695–2699, Rupali Jadhav et al. report on how, by varing the nature and length of alkyl side-chains, the ordering in thin films can be finely tuned. It is found that the I–V characteristics of such photovoltaic devices can be correlated with the photophysical, electrochemical, and structural properties of the respective PPE-PPV copolymers.
