A series of alternating copolymers (PC-AQx,PT-DTAQx,PC-DTAQx,PF-DTAQx,andPBDT-DTAQx) bearing novel planar acenaphtho[1,2-b]quinoxaline (AQx) or 8,11-di(thiophen- 2-yl)acenaphtho[1,2-b]quinoxaline (DTAQx)-acceptor cores have been synthesized via Suzuki or Stille coupling reactions. UV–vis absorption and GIXRD characterization results indicated that the presence of planar DTAQx unit is favorable for the promotion of well-ordered interchain packing in the solid state, and the incorporation of planar electron-donating benzo[1,2-b: 4,5-b′]-dithiophene (BDT) moiety would be propitious to the molecular self-organization. Electrochemical measurement results suggested that four copolymers possess deep HOMO energy level of −5.5 ~ −5.6 eV. The polymer solar cell with structure of ITO/PEDOT:PSS(30 nm)/polymer:PCBM (60 nm)/Bphen(10 nm)/Ag(100 nm) exhibited the highestVocof 0.84 V withPF-DTAQxasp-type polymer, while the best power conversion efficiency (PCE) of 0.9 % was obtained using a blend ofPBDT-DTAQxand PCBM (1:4) as active layer.
