摘要：

Structural, optical, and electrical properties of poly(3-dodecylthiophene) (P3DT) at room temperature have been studied after heat treatments at various temperatures. The crystallinity and the size of the crystallite of P3DT increased after the heat treatment, and the intensity of photoluminescence and the bandgap energy decreased. The electrical conductivity decreased with increasing the heating temperature, while the lattice parameter a decreased but the lattice parameter b increased. These results suggest that the interchain hopping of charge carrier between neighboring pi-conjugation planes is the dominant process in the conductivity and carrier mobility of P3DT. The effects of higher order structure such as crystallinity and the conformation of main chain on electrical and optical properties are discussed.
