제목 | Alternating Electron Donor-Acceptor Conjugated Polymer based on Quinacridone and Quinoxaline for Organic Photovoltaics |
초록 | The characteristics of organic photovoltaics (OPVs) such as low cost, flexibility and fabrication by solution processes have made OPVs a unique member of the solar cell family. Research on developing new materials mainly focuses on the synthesis of new donor-acceptor (D-A) type small band gap polymers that can harvest more sun light to generate higher short-circuit current density (JSC). A quinacridone (QC) which is known as a red-violet pigment, has an ordered structure, self-assembled characteristics and high hole mobility. A quinoxaline (Qx) moiety acts as strong acceptors due to the presence of two imine nitrogen atoms, which has octyloxy chains at the meta-positon (m8) of the phenyl ring for solubility. Moreover, introducing thiophene (T) spacer between D and A unit as π-bridge is extended π-conjugation lengths. In this study, we synthesized D-A type copolymer using quinacridone as the D-unit with m8-quinoxaline as the A-unit by Suzuki coupling reaction. This polymer is showed physical, optical, electrochemical and photovoltaic properties. |
