In view of the fact that luminescent compounds and polymers capable of emitting blue light for a long time and excellent in durability have not been developed, the present invention provides blue light-emitting compounds having special structures, blue light-emitting polymers having special repeating units, processes of producing the compounds, and luminescent elements including the polymers. The most characteristic blue light-emitting compound of the invention has the structure represented by formula (1): wherein R1 is a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, or a special substituent or the invention, two R1s may be the same or different from each other, and n denotes an integer of 1 to 4.
鉴于目前尚未开发出能够长期发出蓝光且具有优异耐久性的发光化合物和聚合物,本发明提供了具有特殊结构的蓝色发光化合物、具有特殊重复单元的蓝色发光聚合物、生产这些化合物的工艺以及包括这些聚合物在内的发光元件。本发明最有特征的蓝色发光化合物具有式(1)表示的结构:其中 R1 是氢原子、具有 1 至 10 个碳原子的烷基或本发明的特殊取代基,两个 R1 可以相同或不同,n 表示 1 至 4 的整数。
