Four polymers that contain alkyl chains branched at different positions on the polymer backbone are prepared. A polymer with 4-decyltetradecyl chains gives an impressive mobility of 3.62 cm(2) V-1 s(-1). This may arise from tighter polymer packing as well as stacking conformation change of the polymer backbone induced by the branching of the alkyl chains.
