제목 Ambipolar Charge Transport in a Donor-Acceptor-Donor-type Conjugated Block Copolymer and Its Gate-Voltage-Controlled Thin Film Transistor Memory
초록 We demonstrate a fully conjugated donor-acceptor-donor (D-A-D) triblock copolymer, PBDTT-PNDIBT-PBDTT, which contains PBDTT as the donor block and PNDIBT as the acceptor block. The polymer was synthesized by end-capping each block with a reactive unit, followed by condensation copolymerization between the two blocks. The physical, optical, and electrochemical properties of the polymer were investigated by comparing those of donor- and acceptor-homopolymers (i.e., PBDTT and PNDIBT), which are the oligomeric monomers, and their blends. On using the newly synthesized block copolymer, ambipolar charge transport behavior and multilevel information were observed in the corresponding thin-film transistor, and the behavior was compared to that of blend film of donor- and acceptor-homopolymers.
