Provided is an organic light emitting device capable of emitting light with high efficiency by incorporating a silyl compound in which a silyl group is directly bonded to an anthracene ring particularly into its light emitting layer. In the organic light emitting device including: a pair of electrodes formed of an anode and a cathode, at least one of which being transparent or semi-transparent; and one or more layers containing an organic compound layer interposed between the pair of electrodes, at least one of the layer containing the organic compound contains the following silyl compound, and a layer containing at least one kind of the silyl compound is a light emitting layer.

highly ordered packing structure of the crystalline state of the unsubstituted derivative is a consequence of intermolecular π-π and CH-π interactions between anthracene units. Photoirradiation of the unsubstituted derivative as a precipitated solution promotes intramolecular [4+4] photocycloaddition reactions between both adjacent pairs of anthracene units to produce a crystalline polycyclic product having
描述了具有 X 形分子结构的 1,2,4,5-四(9-蒽基)苯衍生物的基于 Negishi 偶联的合成。X射线晶体学分析结果表明,未取代衍生物晶态的二维高度有序堆积结构是蒽单元分子间π-π和CH-π相互作用的结果。作为沉淀溶液的未取代衍生物的光辐照促进了两个相邻蒽单元对之间的分子内 [4+4] 光环加成反应,以产生具有独特的 1.700 Å 长碳-碳单键的结晶多环产物。此外,显示近红外吸收和发射的电荷转移复合物,
