Blue light-emitting compounds, blue light-emitting polymers, processes of preparing the blue light-emitting compounds and luminescent element including the blue light-emitting polymers

摘要

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): chemistry chemdraw filechemistry mol file;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.
