抄録

Bis(styrylanthracene) (BSA) derivatives with long alkyl side chains form thin films consisting of large domains (mm-scale) at room temperature by a simple melt-freezing process. It is revealed by X-ray diffraction that the homogeneous domains are in a single-crystal-like solid state. The film assumes a layered structure with π-π stacking parallel to the film plane. The hole mobility of the field effect transistor composed of the monodomain film is almost two orders of magnitude higher than that of the corresponding amorphous film. This result may be due to π-π stacking developed in the carrier transport direction.
