  3,4-Disubstituted Polyalkylthiophenes for High-Performance Thin-Film Transistors and Photovoltaics

  摘要：

  We demonstrate that poly(3,4-dialkylterthiophenes) (P34ATs) have comparable transistor mobilities (0.17 cm(2) V-1 s(-1)) and greater environmental stability (less degradation of on/off ratio) than regioregular poly(3-alkylthiophenes) (P3ATs). Unlike poly(3-hexylthiophene) (P3HT), P34ATs do not show a strong and distinct pi-pi stacking in X-ray diffraction. This suggests that a strong pi-pi stacking is not always necessary for high charge-carrier mobility and that other potential polymer packing motifs in addition to the edge-on structure (pi-pi stacking direction parallel to the substrate) can lead to a high carrier mobility. The high charge-carrier mobilities of the hexyl and octyl-substituted P34AT produce power conversion efficiencies of 4.2% in polymer:fullerene bulk heterojunction photovoltaic devices. An enhanced open-circuit voltage (0.716-0.771 eV) in P34AT solar cells relative to P3HT due to increased ionization potentials was observed.

  The new dialkylated pentathiophene based copolymer was synthesized by Suzuki coupling reaction. The PD5TADF is synthesized and used as an active material for organic thin film transistor (OTFTs). The copolymer has good solubility in common organic solvent such as toluene, tetrahydrofuran (THF), chloroform, chlorobenzene and dichlorobenzene. The number average molecular weight (Mn ) was measured to be 148,000. The TGA curve shows that the polymers exhibit good thermal stability with a weight loss of less than 5% upon heating to 419 °C with glass temperature at 184.9 °C. The ultraviolet (UV) maximum of the polymer was found at 494 nm in solution and 498 nm in the film. A thin-film transistor with PD5TADF was found to exhibit typical p-channel FET characteristics with a hole mobility of 2.6×10−4 cm2/Vs and an on/off ratio of 3.04×104 with a threshold voltage of −4.5 V.

  For the purpose of examining the tuning of photophysical property by fluorine atom substitution, fluorinated and nonfluorinated poly(3,4-dialkylterthiophenes) (PDATs) were synthesized, and their photovoltaic properties were compared. Fluorinated PDATs exhibit a deeper highest occupied molecular orbital energy level than nonfluorinated ones, leading to higher open-circuit voltage in organic solar cells and also enhanced molecular ordering as evidenced by a vibronic shoulder in UV-vis spectra, pi-pi scattering in GIWAXS, and a well-developed fibril structure in TEM, which contributes to efficient charge transport. As a result, the fluorine substitution increases the power conversion efficiency by 20% to 250% as compared with nonfluorinated PDATs.
