  Synthesis and properties of dithienosiloles

  摘要：

  A series of dithienosilole derivatives were synthesized and some of their properties were investigated. UV spectra of dithienosiloles show absorption bands around 350 nm and their cyclic voltammograms display oxidation peaks at about 1.2 V vs. SCE. Nickel-catalyzed coupling of 2,6-dibromodithienosilole with the diGrignard reagent prepared from bis(5-bromothienyl)tetraethyldisilane afforded an alternating polymer composed of a 2,6-dithienyldithienosilole system and tetraethyldisilanylene unit. When the polymer film was doped with FeCl3 vapor, the film became conducting with the maximum conductivity of 7.0 x 10(-3) S/cm. (C) 1998 Elsevier Science S.A.

  Highly luminescent π-conjugated dithienometalloles: photophysical properties and their application in organic light-emitting diodes

  摘要：

  我们已公开了一系列包含Ge、Si、P和S原子作为桥连中心的双环[3,2-b:2',3'-d]金属啉衍生物的异芳环化π-共轭体系的荧光光物理性质和电致发光性质。通过紫外/可见光谱、荧光光谱、瞬态荧光测量和密度泛函理论计算，系统地研究了异芳环化结构对其光物理性质的影响。所有这些化合物在溶液和掺杂的薄膜中都表现出明亮的荧光和高量子产率。此外，采用双噻吩金属啉发射体的OLEDs在实际亮度下表现出高达约6%的外部量子效率。

  Highly photoluminescent acceptor–donor–acceptor (A–D–A) and donor–acceptor (D–A) type compounds with a dithienosilole unit as the donor and perfluorotolyl or dimesitylboryl group(s) as the acceptor were prepared by the reaction of lithiated dithienosilole derivatives with perfluorotoluene or fluorodimesitylborane, respectively. The resulting A–D–A and D–A type compounds showed red-shifted UV absorption and PL bands compared to those of simple dithienosiloles having no acceptor units, reported previously, and were highly photoluminescent in the solid state as well as in solution. Solvatochromic behaviour that would arise from the intramolecular donor–acceptor interaction were observed for the D–A type compounds with respect to the UV absorption and PL spectra. In addition, it was found that bis(dimesitylboryl)dithienosilole and (dimesitylboryl)(methylthio)dithienosilole responded to coexisting fluoride anions, leading to clear UV absorption and PL spectral changes in solutions.

  New fluorene-containing copolymer was prepared via the catalytic dehydrocoupling reaction of 9,9-dipropargylfluorene and 4,4-diphenyl-2,6-dibromo-dithieno-[3,2-b:2,3-d]silole in 44% yield. The resulting polymer was completely soluble in common organic solvents. The thermal behaviors and optical properties of the resulting polymer were measured and discussed. The chemical structure of polymer was characterized by NMR, IR, and UV-visible spectroscopies. The polymer showed characteristic wide UV-visible absorption band and blue PL maximum value at 440nm, which is corresponding photon energy of 2.82eV. The quantum yield (6.44%) of poly(DPF-DTS) was found to be 5times higher than that of poly(DPF-bithiophene)).
