In this study, we achieved high performance organic small molecule transistors by using roll-to-roll slot die coating technique and polymer dielectric layers. By carefully controlling the coating conditions, highly ordered single crystalline thin films could be achieved. Hence, the organic thin film transistor (OTFT) device exhibited an average mobility of 4.2 cm²V⁻¹s⁻¹ and maximum mobility of 6.5 cm²V⁻¹s⁻¹ based on polystyrene (PS) dielectric layer in the ambient air condition, which is among the best values for TIPS-pentacene based devices. The thin film morphology, crystallinity, and optical properties were studied in details. A complementary inverter based on p-type TIPS-pentacene and n-type 6,13-Dicyano pentacene-2,3:9,10-bis(dicarboximide) (PDI-CN) with a high voltage gain of 54 was achieved. Finally, the flexible devices based on roll-to-roll slot die coated PS dielectric and TIPS-pentacene were achieved with a charge carrier mobility of 1.2 cm²V⁻¹s⁻¹.

在这项研究中，我们通过使用卷对卷缝模涂布技术和聚合物介电层获得了高性能有机小分子晶体管。通过仔细控制涂覆条件，可以获得高度有序的单晶薄膜。因此，有机薄膜晶体管（OTFT）器件表现出4.2 cm ² V ^-1 s ^-1的平均迁移率和6.5 cm ² V ^-1 s ^-1的最大迁移率基于在环境空气条件下的聚苯乙烯（PS）介电层，这是基于TIPS-并五苯的设备的最佳值之一。详细研究了薄膜的形态，结晶度和光学性能。实现了基于p型TIPS-并五苯和n-型6,13-​​二氰基并五苯-2,3：9,10-双（二甲酰亚胺）（PDI-CN）的互补逆变器，其高压增益为54。最后，获得了基于卷对卷狭缝模头涂覆的PS电介质和TIPS-并五苯的柔性器件，其载流子迁移率为1.2 cm ² V ^-1 s ^-1。
