Suzuki Coupling Approach for the Synthesis of Phenylene−Pyrimidine Alternating Oligomers for Blue Light-Emitting Material
摘要:
Conjugated oligomers with an alternating phenylene-pyrimidine structure have been synthesized by the successive Suzuki coupling reaction starting from 2-bromo-5-iodopyrimidine. The photoluminescence properties and quasi-reversible redox behavior of these oligomers make them applicable as an active material for a light-emitting device. Blue light-emitting electroluminescent devices with an external quantum efficiency up to 1.8% have been fabricated.

A fluorene-based pyrimidine-containing conjugated oligomer applied in six different layers in an OLED, respectively, used as an electron-transport emitting layer, an emitting layer, a host in the emitting layer, the ETL, a host in the electron-transport emitting layer, and a hole-blocking layer to upgrade light-emitting efficiency and regulate emitting color of the OLED.
