Claims59
An OLED device comprising a light-emitting layer containing a host and a dopant where the dopant comprises a boron compound complexed by two ring nitrogens of a deprotonated bis(azinyl)amine ligand.
The device of claim 5 wherein at least one of the pyridyl groups is substituted.
A compound represented by Formula (1):
- wherein
- A and A′ represent independent azine ring systems corresponding to 6-membered aromatic ring systems containing at least one nitrogen;
- each Xa and Xb is an independently selected substituent, two of which join to form a fused ring group to ring A or A′, respectively, and wherein the fused ring group comprises an aryl or heteroaryl substituent group;
- m and n are independently 0 to 4;
- Za and Zb are independently selected halides;
- and
- 1, 2, 3, 4, 1′, 2′, 3′, and 4′ are independently selected as either carbon or nitrogen atoms.
A compound represented by Formula (1):
- wherein
- A and A′ represent independent azine ring systems corresponding to 6-membered aromatic ring systems containing at least one nitrogen;
- each Xa and Xb is an independently selected substituent, at least one pair of which join to form a ring fused to ring A or A′ at the 3-4 or 3′-4′ position;
- m and n are independently 0 to 4;
- Za and Zb are independently selected halides;
- and
- 1, 2, 3, 4, 1′, 2′, 3′, and 4′ are independently selected as either carbon or nitrogen atoms.
