Organic field-effect transistors（OFETs） based on organic micro-/nanocrystals have been widely reported with charge carrier mobility exceeding 1.0 cm2V-1s-1, demonstrating great potential for high-performance, low-cost organic electronic applications. However, fabrication of large-area organic micro-/nanocrystal arrays with consistent crystal growth direction has posed a significant technical challenge. Here, we describe a solution-processed dip-coating technique to grow large-area, aligned 9,10-bis（phenylethynyl） anthracene（BPEA） and 6,13-bis（triisopropylsilylethynyl） pentacene（TIPSPEN） single-crystalline nanoribbon arrays. The method is scalable to a 5 9 10 cm2 wafer substrate, with around 60% of the wafer surface covered by aligned crystals. The quality of crystals can be easily controlled by tuning the dip-coating speed. Furthermore, OFETs based on well-aligned BPEA and TIPS-PEN single-crystalline nanoribbons were constructed.By optimizing channel lengths and using appropriate metallic electrodes, the BPEA and TIPS-PEN-based OFETs showed hole mobility exceeding 2.0 cm2V-1s-1(average mobility 1.2 cm2V-1s-1) and 3.0 cm2V-1s-1(average mobility2.0 cm2V-1s-1), respectively. They both have a high on/off ratio(Ion/Ioff)>109. The performance can well satisfy the requirements for light-emitting diodes driving.
