英文摘要	three donor-acceptor-donor (d-a-d) conjugated oligomers, i.e., 2att-iid-c8c10, 2att-iid-c6c8 and 2att-iid-c4c6, have been synthesized using anthra[1,2-b]thieno[2,3-d]thiophene (att) as an electron-donor unit and isoindigo (iid) as an electron-acceptor unit by combining the planar and rigid structure of fused aromatics and the strong intramolecular interaction of d-a conjugated molecules, and their semiconducting properties were studied via organic thin-film transistors (otfts). the alkyl chains, which are 2-octyldodecyl (c8c10), 2-hexyldecyl (c6c8) and 2-butyloctyl (c4c6), respectively, were employed in the iid unit in order to study the effect of alkyl bulkiness on the properties of the oligomers. all three oligomers adopted an edge-on alignment in thin films. decreasing the bulkiness or length of the alkyls caused a noticeable improvement of the packing order of the oligomers, leading to a remarkably enhanced charge carrier mobility. 2att-iid-c8c10 could only form the film featured with one-dimensional order. consequently, it exhibited the lowest otft mobility (<0.1 cm(2) v-1 s(-1)). in contrast, both 2att-iid-c6c8 and 2att-iid-c4c6 adopted two-dimensional-ordered packing structures after thermal annealing with a pi-pi stacking distance of similar to 3.6 angstrom, thereby exhibiting promising semiconducting properties. 2att-iid-c4c6 showed the best otft performance with a mobility of 0.72 cm(2) v-1 s(-1). this mobility is among the highest for the solution processible d-a conjugated oligomers to date.
