“…Among different materials, conjugated polymer with alternating donor−acceptor (D−A) with a benzo[1,2-b:4,5-b′]dithiophene (BDT) unit attracts much attention due to the adjustment of the energy gap 2 and mobility by changing the chemical structure. Especially in recent years, a novel donor−acceptor polymer with a fluorinated BDT unit has been synthesized to fabricate bulk heterojunction polymer solar cells and achieved a high power conversion efficiency of 9%, 9 indicating a promising application prospect in organic photovoltaic conversion or semiconductor optoelectronic devices. However, the mobility of this polymer is only 1.5 × 10 −4 cm 2 •V −1 •s −1 determined by Nagano, 10 which is relatively low and accelerates the carrier recombination process, restricting its application in photoelectric devices.…”

The novel two-dimensional graphitic material, graphdiyne (GDY), has attracted great interest due to its superior stability and natural semiconductor characteristic. We realize the obvious improvement of carrier transport1,3-benzothiadiazole) organic polymer semiconductor via adding GDY. The result of the field effect transistor measurement suggests that doping GDY can dramatically improve the on/off ratio and threshold voltage of the organic semiconductor. Especially the mobility of GDY/ PFC film is 2 orders of magnitude higher than that of pristine PFC, demonstrating the important role of GDY dopant. Besides, the carrier diffusion length of GDY/PFC film is also enhanced, suggesting the great potential applications of GDY-modified polymer with donor−acceptor units in organic photoelectric devices.
