摘要

Abstract

Poly(3-hexylthiophene) (P3HT) thin films

obtained by normal spin-coating and solvent vapor assisted spin-coating (SVASP) before and after thermal annealing (TA)

and the corresponding devices were prepared to unravel the microstructure-property relationship

which is of great importance for the development of organic electronics. When SVASP-TA films were used as the active layers of the organic field-effect transistors

a hole mobility up to 0.38 cm

·V

–1

·s

–1

was achieved. This mobility was one of the highest values and one order of magnitude higher than that of the normal spin-coating films based transistors. The relationship between the microstructure and the device performance was fully investigated by UV-Vis absorption spectra

grazing incident X-ray diffraction (GIXD)

and atomic force microscopy (AFM). The impressive mobility was attributed to the high crystallinity and ordered molecule packing

which stem from the synergistic effects of SVASP and thermal annealing.
