  Synthesis and characterization of N-carbazole end-capped oligofluorene-thiophenes

  摘要：

  A series of novel N-carbazole end-capped oligofluorene-thiophenes with one, two, three, and four thiophene rings were synthesized using either palladium catalyzed cross-coupling reaction or nickel-catalyzed reductive dimerization. All the oligomers have been characterized by H-1, C-13 NMR, FTIR, UV-vis, PL spectroscopy and mass spectrometry. It has been demonstrated that the optical, thermal, and electrochemical properties of these materials can be tuned by varying the conjugation length of the oligothiophene segment. The terminal carbazole and fluorene moieties of the resulting materials are beneficial for their morphology, conjugation length, and solubility. These bright fluorescent, thermally and electrochemically stable compounds have potential applications as light-emitting and hole-transporting layers in organic light-emitting devices.

  Colour tuning of blue electroluminescence using bipolar carbazole–oxadiazole molecules in single-active-layer organic light emitting devices (OLEDs)

  摘要：

  在一系列新的双极性咔唑-2,5-二芳基-1,3,4-恶二唑杂化分子 1-7 中，采用了一种综合通用策略来调节发光颜色。报告了它们的合成、溶液吸收和发射特性以及循环伏安数据。使用 DFT（密度泛函理论）的计算表明它们具有有利于双极电荷传输的分子轨道。单活性层有机发光器件 (OLED) 是通过热蒸发法使用双极性化合物作为 ITO:PEDOT-PSS:X:Ca/Al (X = 1-7) 结构中的发射极来制造的。该系列化合物的结构与性能关系的评估重点是 OLED 性能和发射颜色。 HOMO-LUMO 间隙通过 1-7 分子亚基的系统修饰而变化，从而使电致发光的颜色从深蓝色 (CIE x,y 0.157, 0.079) 调整到绿色 (CIE x, y 0.151, 0.096)。由于分子的良好加工性、双极结构、颜色可调性以及使用简单器件架构的 OLED 的高效性能，这些材料对于进一步开发非常有吸引力。

  A series of N-carbazole end-capped oligofluorenes (CFn, n = 1–3) were synthesized. The 9-position of the carbazole moiety was attached to the terminal ends of the oligofluorene cores using an Ullmann coupling reaction. These molecules exhibit red shifts in absorption and photoluminescence spectra with respect to the number of fluorene units and excellent electrochemical reversibility. They were found

• Combined experimental and theoretical study of one- and two-photon absorption properties of D–π–A–π–D type bis(carbazolylfluorenylethynyl) arene derivatives: Influence of aromatic acceptor bridge

  This article reports the design and synthesis of five new donor-pi-acceptor-pi-donor derivatives where carbazolylfluorenyl serves as donor; arenes serve as central core acceptors, and acetylene group as a it bridge. Comprehensive one- and two-photon absorption properties of these compounds were studied experimentally and theoretically. The two-photon absorption cross-sections were measured by using two-photon excited fluorescence spectrometer and showed significant enhancement from 560 to 2600 GM. In general, the two-photon absorption cross-section values increase with respect to the strength of the acceptor bridge (arenes) in the order of benzene < thiophene < fluorene < anthracene < benzothiadiazole and with the increase of excited state transition dipole moments. The calculated two-photon absorption cross-section values and trends are in good agreement with the experimental results. The combination of large two-photon absorption cross-sections and high emission quantum yields makes the dyes attractive for applications involving two-photon excited fluorescence.
