Abstract: We report a new n-type single-crystalline microribbon based on a chlorophenyl-substituted perylene tetracarboxylic diimide derivative via solution-phase self-assembly. Electronic transport, environmental stability, and photoresponse properties of these microribbons are studied using field-effect transistors. Transistors based on a network of the as-prepared microribbons have moderate electron mobilities and ON/OFF current ratios on the order of 10(-3) cm(2)/V.s and 10(3)-10(4), respectively. The lifetime test of microribbon devices under various humidity conditions is found to be very sustainable over 100 days. Moreover, illuminating these microribbons could profoundly induce photocurrents in the visible light range, presenting good responsivity of 9.5 A/W and a high external quantum efficiency up to 2000% under 1.9 mW/cm(2). In addition, these microribbon devices are processed from solution-phase at temperatures below 100 degrees C, making the technology a viable candidate for low-cost and plastic-based organic optoelectronic applications.
