  Poly(3-dodecylthienylenevinylene)s: Regioregularity and Crystallinity

  摘要：

  A series of poly(dodecylthienylenevinylenes), C-12-PTVs-a: b, with tunable regioregularity and solubility have been synthesized using two isomeric comonomers with molar ratios from 0:10 to 5:5, and characterized by NMR spectroscopy, differential scanning calorimetry, absorption spectroscopy, cyclovoltammetry, and X-ray diffraction. For the first time, the aromatic and olefinic H-1 NMR peaks of regioregular head-tail C-n-PTVs are dearly assigned. No major difference in XRD peak intensity is observed among regiorandom and fully regioregular C-12-PTVs. V-oc of C-12-PTVs-a:b and PC60BM blend solar cells are in the range of 0.43 to 0.51 V and consistently decrease as regioregularity is reduced. C-12-PTV-3:7:PC60BM solar cells give the highest short-circuit current and practically same efficiency as that of C-12-PTV-1:9:PC60BM devices. The results suggest a new strategy to enhance processability of optoelectronic polymers without sacrificing their crystallinity and device performance.

  demonstrate that 3-alkyl(thienylene-vinylene) oligomers form part of the polyene family. The shortest (n = 2) oligomer emits from the bright 1Bu state, while fluorescence in oligomers with n = 3, 4 is from the formally dark 2Ag state, allowed via Herzberg–Teller vibronic coupling to the nearby bright 1Bu state as described for diphenyl-polyenes. Longer oligomers and the polymer are essentially non-emissive

  聚（3-烷基（噻吩基-亚乙烯基））（P3TV）及其较长的低聚物具有可忽略不计的低光致发光量子产率，然而，其低产率的原因目前存在争议。在这里，我们通过迭代 Horner-Wadsworth-Emmons 反应制备了一系列具有n = 2-8 重复单元的区域规整 (3-十二烷基) 噻吩基-亚乙烯基低聚物，并报告了它们的稳态、瞬态吸收和发射光谱。此处显示的结果表明 3-烷基（噻吩基-亚乙烯基）低聚物构成多烯家族的一部分。最短的 ( n = 2) 低聚物从明亮的 1B u状态发射，而n = 3、4 的低聚物中的荧光来自正式的暗 2A g状态，允许通过Herzberg-Teller 电子振动耦合到附近明亮的 1B u状态，如二苯基多烯所述。较长的低聚物和聚合物基本上是非发射性的，因为 2A g状态不能再从 1B u状态借用强度。我们证明光谱形状、光致发光量子产率和瞬态光谱行为都可以使用具有弱电子相关性的多烯模型来解释。
