제목 Novel Quinoid-type Conjugated Molecules and Polymers for High Performance Organic Field-Effect Transistors
초록 Organic field-effect transistors (OFETs) based on organic semiconductors have intensive interests both in the academic and industrial fields due to their application in low-cost and flexible electronics. The quinoidal structure has been considered as a promising building block to achieve efficient charge transport due to their high structural planarity arisen from a double bond characteristics. Here, isomer-free quinoid compound and conjugated polymers based on a novel quinoidal platform are synthesized through short and facile synthetic steps and characterized. Among them, OFETs based on poly(quinoidal thiophene-bithiophene) (PQuT-BT) prepared by off-center spinning showed the unprecedent highest hole mobility of 8.09 cm2 V-1 s-1 among reported quinoidal polymers. Moreover, OFETs prepared by PQuT-BT showed high performance as well as exceptional uniformity for large area devices arisen from chain alignment via advanced coating methods.
