英文摘要	theoretical investigations of hole-transport properties in two naphtho[2,1-b:6,5-b']difuran derivatives as novel p-type organic semiconductor based on the marcus-hush theory combining quantum mechanics are carried out. this work focuses on the effects of carbon chain on molecular orbitals, partial charge difference, ionization potential, internal energy relaxation, and hole-transport behaviors. through computational modeling, we are shedding light on the favorable function of c8-dpndf single crystal as p-type organic material. with the introduction of octyl group, c8-dpndf single crystal possesses high hole-transfer mobilites (1.589 cm(2) v-1 s(-1)) and remarkable anisotropic behavior. the simulated anisotropic mobility curve of c8-dpndf demonstrates the maximum value of the mobility appears when the measuring conducting channel is along the b-axis of the single crystal. the adiabatic ionization potential (aip) and vertical ionization potential (vip) of c8-dpndf are about 6.312 and 6.399 ev, that is, slightly smaller than those of dpndf. the relatively small ip values can ensure effective hole injection from the source electrode. the data obtained from the present work can be used to prove that c8-dpndf molecule has the potential to develop into high-efficient p-type organic semiconductor materials, whose hole-transport mobility can be further improved when the measuring transistor channel is controlled carefully.
