The copolymer showed good solubility in chloroform, chlorobenzene, and dichlorobenzene. The thermogravimetric analysis curve showed that the copolymer had good thermal stability with weight loss of less than 5% at 341 °C. The UV absorption maximum of the polymer appeared at 550 nm in solution and 600 nm in the film. The HOMO and LUMO of the copolymer were -5.50 eV and -3.63 eV, respectively. The copolymer exhibited the best performance when the PC61BM ratio was 1:2 (w/w %), with a JSC of 3.56 mA/cm2, a VOC of 0.45 V, an FF of 0.27%, and a PCE of 0.43%. A thin film transistor with PDT-TBT as the active layer showed mobility of 5.02×10-3 cm2/Vs, an on/off ratio of 1.19×105 and a threshold voltage of -22.75 V.
