Novel Alkoxyanthracene Donor and Benzothiadiazole Acceptor for Organic Thin Film Transistor and Bulk Heterojunction Organic Photovoltaic Cells |
| 초록 |
Novel alkoxy anthracene (ODA)-based polymeric semiconductors were designed for polymer solar cell applications. Alkoxyanthracene, which contains many p electrons and electron donating group, was easily synthesized. The copolymers, poly(alkoxy anthracene-alt-thiophene benzothiadiazole thiophene) poly(ODA-TBT) and poly(alkoxy anthracene-alt-benzothiadiazole) poly(ODA-BT), have been obtained by Suzuki coupling polymerization. Both polymers have ODA unit as a donor and benzothiadiazole as an acceptor. ODA-TBT has thiophene linkages between ODA and benzothiadiazole. The optical, thermal, and electrochemical properties have been investigated by UV–visible absorption, thermal gravimetric analysis, differential scanning calorimetry, and CV. The better device performance of poly(ODA-BT) is attributed to its charge transfer ability and enhanced mobility and crystallinity although poly(ODA-BT) does not have extended pconjugation due to twisted structure compared with poly(ODATBT). |
