摘要:
There are provided novel blue light-emitting organic electroluminescent polymers having a main chain consisting of 9,10-diphenylanthracene and vinylene, and electroluminescent devices using the same. With the introduction of substituents which are of high thermal stability and are capable of steric hindrance at the alpha position of the vinyl group, the electroluminescent polymers make it easy to conduct inter- and intra-molecular energy transfer, and the injection and transportation of holes or electrons, as well as restraining p-stacking between polymer chains. Also, the prevention of intermolecular two- and three-dimensional interference by the introduced bulky substituents leads to reduced extinction of excitons, whereby the organic electroluminescent device can emit blue light at high luminous efficiency.
摘要:
Provided are main-chain type or side-chain type high-molecular compounds wherein at least one metal complex moiety bearing two or more ligands in the structure is introduced into the main chain or the side chain. In the main-chain type high-molecular compound, at least one ligand of the metal complex moiety participates in constituting the main chain of the compound and the carbon or oxygen atom of the ligand is bonded to the metal atom, while in the side-chain type high-molecular compound, the main chain has a conjugated structure, preferably conjugated double bonds. The ligands are preferably bidentate ones having organic cyclic structures, though they include linear and cyclic ones. Each ligand is bonded to the central metal atom, preferably iridium, through at least one carbon or oxygen atom constituting the ligand. Organic luminescent devices equipped with light-emitting layers containing the high-molecular compounds as the luminescent material little cause concentration quenching and exhibit high luminous efficiency and excellent stability.
