Novel blue luminescent materials for organic electroluminescent devices

摘要

A luminescent material (I) contains a compound of formula (1) where n = 2, 3 m = a divalent or trivalent metal G = 6-24C aryl or heteroaryl group, optionally substituted with 1-8C alkyl or haloalkyl, 1-18C alkoxy or haloalkoxy, halogen, cyano, amino, amido, sulphonyl, carbonyl, aryl or heteroaryl R1, R2 = H, 1-8C alkyl or haloalkyl, halogen, cyano, amino, amido, sulphonyl, carbonyl or a 5-24C fused aromatic ring.
