    逐步改进基于氟喹喔啉的低带隙聚合物的光伏性能
    摘要:
    通过Stille偶联反应合成了一系列具有典型供体-π-受体构型的氟化喹喔啉类聚合物。供电子的二烷氧基取代的苯并二噻吩(BDT)通过噻吩桥与吸电子的2,3-二苯基喹喔啉(DPQ)受体连接。为了研究强吸电子基团的效果,氟原子已经被系统地在上DPQ单元的各种位置,如6,7-位置时,结合对位上的2,3-位上的苯基取代基的位上,和两个地方都可以买到PBDT-QxF,PBDT-FQx和PBDT-FQxF, 分别。由于氟原子的显着贡献,与它们的非氟化对应物PBDT-Qx相比,这些聚合物显示出截然不同的光学和电化学性质。此外,当采用以下配置的倒置型聚合物太阳能电池(PSC)时,功率转换效率(PCE)逐渐以PBDT-Qx,PBDT-QxF,PBDT-FQx和PBDT-FQxF的顺序改善。制备了ITO / ZnO /聚合物:PC 71 BM / MoO 3 / Al。特别是PBDT-FQxF,在6,7位和对位上有四个氟原子在DPQ的2

    Three new quinoxaline-based derivatives, end-functionalized with 2,3,5,8-tetraphenyl (3), 2,3- diphenyl-5,8-di(thiophen-2-yl) (4), and 2,3-diphenyl-5,8-bis(5-phenylthiophen-2-yl) (5) were synthesized, characterized, and incorporated as organic semiconductors in top-contact/bottom-gate organic thin-film transistors (OTFTs). Thermal, optical, and electrochemical properties of the newly developed compounds were fully investigated. For the fabrication of thin films of all three compounds, solution-shearing (SS) and vacuum deposition method were employed. Thin films of compound 5 showed p-channel characteristics with hole mobilities as high as 2.6×10-5 cm2/Vs and current on/off ratio of 1.8×105 via solution process and 1.9×10-4 cm2/Vs and current on/off ratio of 3.5×106 via vacuum deposition.

    Copolymers based on benzodithiophene and quinoxaline, represented by 4,8-bis(5-(3,4,5-tris(octyloxy)phenyl)thiophen-2-yl)benzo[1,2-b:4,5-b′]dithiophene (TOBDT) and 2,3-diphenyl-5,8-di(thiophen-2-yl)quinoxaline (TQ1) or 10,13-bis(4-(2-ethylhexyl)thiophen-2-yl)dibenzo[a,c]phenazine (TQ2), were synthesized via a Stille coupling reaction. By increasing the conjugation in the TQ2 unit, the polymer based on TQ2 showed a narrower band gap (Eg), a lower highest occupied molecular orbital energy level and enhanced interchain π–π interactions. Polymer solar cells based on TQ2 showed a simultaneous enhancement of the open-circuit voltage (Voc), short-circuit current density (Jsc) and fill factor (FF) compared with polymer solar cells based on the TQ1 polymer. A good power conversion efficiency of 4.24% was achieved by solar cells based on the TQ2 polymer and [6,6]-phenyl-C71-butyric acid methyl ester composite. These preliminary results indicate that increasing the acceptor unit (quinoxaline) conjugation is an effective way of improving the performance of polymer solar cells.

    Four donor acceptor (D-A) type copolymers, namely, poly9,9-dioctylfluorene-2,7-diyl-alt-5-8-dithien-2-yl-2,3-dephenylquinoxaline-5,5',5 ''-diyl}(PF-DTQx), polyN-[1-(2'-ethylhexyl)-3-ethyl-heptanyl]carbazole-2,7-diyl-alt-5,8-dithien-2-yl-2,3-diphenylquinoxaline-5',5 ''-diyl} (PC-DTQx), poly5,11-di(1-decylundecyl)indolo[3,2-b]carbazole-3,9-diyl-alt-5,8-dithien-2-yl-2,3-diphenylquinoxaline-5',5 ''-diyl} (PIC-DTQx), and polyN-[1-(2'-ethylhexyl)-3-ethylheptanyl]-dithieno[3,2-b:2',3'-d]-pyrrole-2,6-diyl-alt-5,8-dithien-2-yl-2,3-diphenylquinoxaline-5',5 ''-diyl} (PDTP-DTQx), were synthesized by Suzuki or Stille coupling reactions. By changing the donor segment, the band gaps and energy levels of these 5,8-dithien-2-yl-2,3-diphenylquinoxaline (DTQx)-based polymers could be finely tuned. PDTP-DTQx exhibited the narrowest band gap of 1.56 eV and the absorption edge extended to 770 nm. We investigated bulk heterojunction type polymer solar cells (PSCs) based on these copolymers as the electron donor materials, and [6,6]-phenyl C-61 butyric acid methyl ester (PCBM) or [6,6]-phenyl C-71 butyric acid methyl ester (PC70BM) as the acceptor. The power conversion efficiency (PCE) of the PSCs was in the range of 1.17-3.23% under AM 1.5 illumination (100 mW/cm(2)).
