제목 Selenophene-Based Low-Bandgap Donor–Acceptor Polymers for use in Organic Thin Film Transistors
초록 Recently, diketopyrrolopyrrole (DPP) has been frequently employed as an acceptor building unit for high-performance semiconducting polymers, because it is a strong symmetric acceptor having a fused ring to impose coplanarity and promote intermolecular interaction. Evidently, DPP-based conjugated copolymers are seriously considered as potential materials for organic field effect transistors (OFETs). Herein we describe the synthesis of a new series of polymers containing DPP and selenophene moieties in the repeating group. The copolymers are highly crystalline and displayed very promising charge transport phenomenon. Thermal analysis, cyclic voltammetry and absorption spectroscopy were employed to investigate their intrinsic material properties. Eventually, we fabricated field effect transistor to study their p-type semiconducting property.
