in moderate yields. Their optical properties were investigated via UV–vis absorption, fluorescence and phosphorescence spectroscopies, which indicated that the σ*–π* conjugated system expanded owing to the silicon atoms. Some of the compounds exhibited enhanced luminescence, larger Stokes shift, and phosphorescence in comparison with 9,9,10,10-tetramethyl-9,10-dihydroanthracene. Density functional theory
通过1,2-双(二甲基甲硅烷基)芳烃与1,2-二碘芳烃的钯催化偶联反应,合成了各种含硅六元环分子。通过紫外可见吸收光谱,荧光光谱和磷光光谱研究了它们的光学性质,这表明σ* –π *共轭体系由于硅原子而扩展。与9,9,10,10-四甲基-9,10-二氢蒽相比,某些化合物具有增强的发光,更大的斯托克斯位移和磷光。还进行了密度泛函理论(DFT)研究,以研究化合物的光物理性质。
