Abstract:
1. An OLED device comprising a light-emitting layer containing a light emitting bis(azinyl)methene boron complex compound represented by Formula (1): wherein A and A′ represent independent azine ring group systems corresponding to 6-membered aromatic ring systems containing at least one nitrogen; each X m and n are independently 0 to 4; Y is H or a substituent: Z wherein provided that 1, 2, 3, 4, 1′, 2′, 3′, and 4′ are independently selected as either carbon or nitrogen atoms; and provided that the selection of each X provided further that there is at least one substituent on the fused ring system sufficient to provide a wavelength of maximum emission of less than 520 nm at a concentration of <10
