High-Performance Air-Stable Solution Processed Organic Transistors

Solution-processed organic field-effect transistors (SPOFETs) have attracted wide interest in the past decade as they hold great promise for roll-to-roll production of ubiquitous flexible electronic circuits, displays, etc. by low-cost unconventional means, such as screen and inkjet printing. Despite the tremendous progress, it remains a challenge to fabricate consistently high-mobility air-stable SPOFETs at low-temperature for practical applications. Here we present high performance (mobility up to 0.2-0.4 cm

), air-stable (monitored over 200 days without noticeable degradation) SPOFETs based on a developed solution process using asymmetric soluble small molecule semiconductor, 4T-TMS. The systematic experimental study on the process control for these SPOFETs was also be reported.
