Synthesis and structure-property relationships of new donor-acceptor type conjugate copolymers |
| 초록 |
Two donor-acceptor conjugated copolymers comprised of a novel dithienophosphole (DTP) as the acceptor unit and bithiophene (BT) or decylthiophenebenzodithiophene (DTBDT) as the donor unit were synthesized and characterized to elucidate the relationship between donoreacceptor (DeA) architecture and organic field-effect transistors (OFETs) performance. These characteristics of DeA copolymers were affected by the structural suitability of donor and acceptor units. Poly(DTP-BT) had an ordered structure that facilitated charge carrier transfer. The crystallinity of poly(DTP-BT) increased as annealing temperature (Tann) increased. In contrast, poly(DTP-DTBDT) was amorphous regardless of Tann due to the long alkyl chains of the DTBDT units. OFET devices made with poly(DTP-BT) and annealed at 200 C exhibit a highly crystalline morphology and a relatively high field-effect mobility (4.9 103 cm2/(V$s)). |
