抄録

The present study takes advantage of molecular self-assembly of Oligofluorenes for the preparation of organic field-effect transistors. These new materials permit a systematic investigation of carrier mobility in monodomain and polydomain glassy-nematic films in addition to glassy-amorphous films. It was found that mobility increases with oligomer length and that the mobility of a long-chain polymer is limited by its persistence length. At a sufficient molecular length, an oligomer's mobility was shown to surpass that of its polymer analogue. For instance, a monodomain film of a dodecafluorene exhibited a hole mobility of 0.012 cm 2/Vs, an enhancement over a glassy-amorphous film by a factor of 800.
