Organic Electrofluorescent Materials Using Pyridine-Containing Macrocyclic Compounds

摘要

Novel pyridine-containing macrocyclic compounds,such as 6,12,19,25-tetramethyl-7,11,20,24-dinitrilo-dibenzo [b,m]1,4,12,15-tetra-azacyclodoc osine(TMCD),were synthesized and used as electron transport layer in organic electroluminescent devices.Devices with a structure of glass/indium-tin oxide/arylamine derivative/ tris(quinolinolato)aluminum(Ⅲ)(Alq)/TMCD/LiF/Al exhibited green emission from the Alq layer with external quantum efficiency of 0.84% and luminous efficiency of 1.3 lm/W.The derivatives of TMCD were synthesized and characterized as well.These compounds were also found to be useful as the electron-transporting materials in organic electroluminescent devices.
