title: Influence of alkyl chain branching positions on the hole mobilities of polymer thin-film transistors.
abstract: 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.
