英文摘要	two benzothienobenzothiophene (btbt)-based conjugated oligomers, i.e., 2,2'-bi[1]benzothieno[3,2-b][1]benzothiophene (1) and 5,5'-bis([1]benzothieno[3,2b][1]benzothiophen-2-yl)-2,2'-bithiophene (2), were prepared and characterized. both oligomers exhibit excellent thermal stability, with 5% weight-loss temperatures (t-l) above 370 degrees c; no phase transition was observed before decomposition. the highest occupied molecular orbital (homo) levels of 1 and 2 are -5.3 and -4.9 ev, respectively, as measured by ultraviolet photoelectron spectroscopy. thin-film x-ray diffraction and atomic force microscopy characterizations indicate that both oligomers form highly crystalline films with large domain sizes on octadecyltrimethoxysilane-modified substrates. organic thin-film transistors with top-contact and bottom-gate geometry based on 1 and 2 exhibited mobilities up to 2.12 cm(2)/v.s for i and 1.39 cm(2)/v.s for 2 in an ambient atmosphere. 1-based devices exhibited great air and thermal stabilities, as evidenced by the slight performance degradation after 2 months of storage under ambient conditions and after thermal annealing at temperatures below 250 degrees c.
