| 摘要: | 研究期間：10108~10207;Organic field-effect transistors (OFETs) have attracted intensive attention for potential applications in flexible displays, low-cost electronic papers, RFID components, and smart textiles, as well as smart memory/sensor elements in the automotive and transportation industries. During the past three years, we have developed a facile One-pot [X+1+Y] synthetic routes for preparation of DTT (dithienothiophene), TTA (tetrathienoacene) and PTA (pentathienoacene). A couple of new derivatives based on these poly fused-thiophene ring systems have been prepared. For p-type materials development, asymmetric DTT derivatives had been obtained with mobility up to 0.5 cm2V-1s-1. Stable semiconductor materials based on benzo[d,d’]thieno [3,2-b;4,5-b’]dithiophene system (BTDT) had been synthesized with mobility up to 0.7 cm2V-1s-1. Soluble BTDT-based material had demonstrated mobility up to 0.6 cm2V-1s-1, via spin coating. For n-type materials development, new candidates based on TTA had been obtained with mobility up to 0.37 cm2V-1s-1. Soluble BSTs has shown mobility up to 0.15 cm2V-1s-1, via solution process. Here in this project, these new developed poly fused-thiophenes will be prepared for finishing the paper publication. Meanwhile, via our [X+1+Y] one-pot synthetic routes, new poly fused-thiophenes will be explored and their electronic performance in OTFT will be evaluated.Organic field-effect transistors (OFETs) have attracted intensive attention for potential applications in flexible displays, low-cost electronic papers, RFID components, and smart textiles, as well as smart memory/sensor elements in the automotive and transportation industries.
