| 英文摘要 | oligo(2,6-naphthalene)s (nns) with the number of repeating unit (n) of 3-5 and dioctyl substituted trimer (do-3n) and tetramer (do-4n) were synthesized and characterized. except of do-4n that decomposed at 331 degrees c, all other oligomers display good thermal stability with 5% weight loss temperatures beyond 350 degrees c. for 4n and do-4n, only one phase transition corresponding to melting can be found. however, do-3n and 5n exhibit multiple phase transitions. the film absorption maximum of the oligomers at the long wavelength exhibits a red-shift with increasing the number of repeating unit. meanwhile, the highest occupied molecular orbital (homo) levels increase from -5.96 ev of 3n to 5.91 ev of 4n and then 5.85 ev of 5n. the introduction of octyl group has negligible effect on the photophysical properties. highly ordered films of 4n, 5n, do-3n and do-4n in which the molecules orient with their long axis standing on the substrates can be prepared by vacuum deposition. organic thin-film transistors (otfts) with top-contact and bottom-gate geometry have been fabricated based on these films. the introduction of octyl groups results in the films with higher order and therefore higher field-effect mobilities (mu) of otft devices. among these oligomers, do-3n exhibits the highest mobility of 0.50 cm(2)/v s when the film deposited on the octyltrichlorosilane (ots) modified substrate.
