제목 Diketopyrrolopyrrole–based Conjugated Terpolymer for High Performance Organic Electronic Devices
초록 Organic semiconductors have been intensely studied due to their promising advantages as low-cost, flexible, and large-area devices. In order to tune energy level between highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), the alternating acceptor-donor-acceptor-donor’(A-D-A-D’) terpolymer structure was proposed as a suitable method to enhance the electronic device performance. In this study, we synthesized diketopyrrolopyrrole (DPP)-based alternating conjugated terpolymers bearing two different donating units such as fluorene and bithienyl unit, and applied them to electronic and optoelectronical devices. Thermal analysis, electrochemical analysis and absorption spectroscopy were employed to investigate their material properties. Eventually, the electronic and optoelectronic properties of A-D-A-D’ terpolymers were investigated and compared with those of the corresponding A-D and A-D’ copolymers.
