英文摘要	Oligoarenes as an alternative group of promising semiconductors in organic optoelectronics have attracted much attention. however, high-performance and low-cost opto-electrical devices based on linear asymmetric oligoarenes with nano/microstructures are still rarely studied because of difficulties both in synthesis and high-quality nano/microstructure growth. here, a novel, linear asymmetric oligoarene 6-methyl-anthra[2,3-b]benzo[d]thiophene (me-abt) is synthesized and its high-quality microribbons are grown by a solution process. the solution of me-abt exhibits a moderate fluorescence quantum yield of 0.34, while the microribbons show a glaucous light emission. phototransistors based on an individual me-abt microribbon prepared by a solution-phase self-assembly process showed a high mobility of 1.66 cm(2)v(-1) a large photoresponsivity of 12 000 a w(-1), and a photocurrent/dark-current ratio of 6000 even under low light power conditions (30 mu w/cm(2)) the measured photoresponsivity of the devices is much higher than that of inorganic single-crystal silicon thin film transistors. these studies shod boost the development of the organic semiconductors with high-quality microstructures for potential application in organic optoelectronics.
