摘要

Application-oriented growth of patterned organic semiconductor (OSC) thinfilms with a single domain is a nonnegotiable requirement for the manufacturingof high-performance organic electronic devices. However, the prevalentselective-wetting patterning method remains a challenge in controlling thedensity of nucleation events in microscale spaces, resulting in thin filmswith high grain boundary density and no preferential orientation spherulites.Herein, a simple double-blade-coating printing technique using a combinationof wetting-patterned substrates to produce an array of highly crystallineOSC thin films is developed. Specifically, the approach confines the OSCcrystallization on a molecular-flat water surface in specific areas, enablinga significant reduction in the number of nuclei. Consequently, patterned2,7-dioctyl[1]benzothieno[3,2-b] benzothiophene (C8-BTBT) thin films comprisingsingle-crystal domains are achieved with an exceptionally high yield of62.5%. The organic field-effect transistor array developed from such patternsof C_8-BTBT single-crystalline films exhibits an excellent average mobilityof 11.5 cm~2 V~(?1) s~(?1) which is 12.5-fold higher compared to that of the referencesample fabricated via conventional single-blade coating. It is believedthat this approach can be widely applied to other soluble organic materials,thereby opening up opportunities for fabricating multicomponent integratedelectronics.
