    Synthesis and Structure-Linear and Structure-Nonlinear Optical Properties of Multi-Dipolar Zigzag Oligoaryleneethynylenes
    摘要:
    A novel series of monodisperse, multi-dipolar zigzag oligoaryleneethynylenes DA(n) and D-Ar-A(n), bearing electron-donating dibenzothiophene and electron-accepting dibenzothiophene dioxide as arenes, with up to six charge-transfer (dipolar) units have been designed and synthesized by palladium-catalyzed Sonogashira coupling reactions. The linear and nonlinear optical properties of these multi-dipolar oligoaryleneethynylenes can easily be modified or enhanced by incorporating/extending with various central aryleneethynyl moieties such as phenylethynyl, oligo(9,9-dibutylfluorenyl)ethynyl, and oligothienylethynyl within the donor-acceptor units. Interestingly, the absorption and emission of these zigzag oligoaryleneethynylenes are not dependent on the number of covalently linked dipolar chromophores; however, the fluorescence quantum efficiencies consistently decrease with increased number of covalently linked dipolar units. These zigzag oligoaryleneethynylenes exhibit a linear increase in the two-photon absorption (TPA) cross-sections with increased number of covalently linked dipolar units without red-shifting the absorption and emission spectra. In addition, very large TPA cross-sections in the femtosecond regime (sigma(800) = 1306 GM in DMF or sigma(750) = 1522 GM in CH2Cl2) were obtained for D-TF-A(4) despite the moderate strength of the donor-acceptor pair. Our results suggest that the TPA properties of these zigzag oligoaryleneethynylenes including TPA wavelength and TPA cross-section can easily be tuned by means of modifying the central aryleneethynylene units and increasing the number of dipolar units, respectively. This approach provides an alternative means to tune or enhance the TPA cross-section at a specific wavelength.

    摘要:
    摘要利用Ullmann C–N偶联反应,合成了一组由电子接受的二苯并噻吩核和给电子的低聚咔唑树枝状分子组成的新型咔唑树枝状聚合物,即G1SF和G2SF。树枝状聚合物的设计方式使其在普通有机溶剂中显示出良好的溶解性,在高达430°C的分解温度(T d)下具有出色的热化学稳定性,并且在-5.45 eV至-5.37 eV的范围内具有较高的HOMO水平。密度泛函理论计算(DFT)的结果表明,G2SF在空穴和电子传输部分几乎完全分离了HOMO和LUMO能级。而G1SF可能仅由于分子内电荷转移而使HOMO和LUMO能级仅部分分离。以树枝状大分子为主体,传统绿色铱磷光体为掺杂发射体,通过旋涂法制备了绿色磷光OLED。在环境条件下,G1SF的最大亮度效率(ηL)为19.83 cd A -1,G2SF的最大外部量子效率为5.85%,G2SF的最大外部量子效率为15.50 cd A -1和4.57%。

  • A general procedure for the synthesis of methylthio-, methylseleno- and methyltelluro-substituted aromatic compounds
    作者:Lars Engman、Jonas S.E. Hellberg
    DOI:10.1016/0022-328x(85)80366-1
    日期:1985.12
    A one-pot procedure is described which allows the facile introduction of one or two methylchalcogeno groups into a variety of monobromo or dibromo aromatics. The bromo compounds were converted to their corresponding lithio derivatives by treatment with t-butyllithium in tetrahydrofuran at −78°C, and these derivatives were then treated, at ambient temperature with elemental sulfur, selenium, or tellurium
    描述了一种一锅法,其允许容易地将一个或两个甲基硫属元素基引入各种单溴或二溴芳族化合物中。通过在-78℃下在四氢呋喃中用叔丁基锂处理,将溴代化合物转化为其相应的硫代衍生物,然后在环境温度下用元素硫,硒或碲处理这些衍生物。最后,将所得的硫醇锂,硒酸锂和碲酸锂用甲基碘甲基化,以得到各种甲基硫属元素取代的芳族化合物的良好收率(通常为50-80%)。该方法不能用于合成邻二取代化合物或同时引入三个甲基硫属元素基。
