Abstract

The complexes disclosed herein are cyclometalated metal complexes of Formula (I) that are useful for full color displays and lighting applications.

First claim

What is claimed is:

1. A complex represented by the following structure:

wherein:
M is Pt or Pd;
Y 1a represents O, S, S(O), S(O) 2 , Se, Se(O), Se(O) 2 , N, NR 5a , P, PR 5a , As, AsR 5a , O═NR 5a , O═PR 5a , O═AsR 5a , B, BR 5a , SiR 5a , SiR 5b R 5c , CR 5a , or CR 5b R 5c , where R 5b , R 5b , and R 5c each independently represents hydrogen, substituted or unsubstituted C 1 -C 4 alkyl, or substituted or unsubstituted aryl;
R 3 and R 4 each independently represents hydrogen, halogen, hydroxy, amino, nitro, thiol, Si(C 1 -C 4 alkyl) 3 , substituted or unsubstituted C 1 -C 4 alkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted aryl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heteroaryl, or substituted or unsubstituted heterocycloalkyl;
each R 5 and R 6 independently represents hydrogen, halogen, hydroxy, amino, nitro, thiol, Si(C 1 -C 4 alkyl) 3 , substituted or unsubstituted C 1 -C 4 alkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted aryl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heteroaryl, or substituted or unsubstituted heterocycloalkyl; and
each of u and v is an integer, valency permitting.

2. A complex represented by the following structure:

wherein:
M is Pt or Pd;
Y 1a represents O, S, S(O), S(O) 2 , Se, Se(O), Se(O) 2 , N, NR 5a , P, PR 5a , As, AsR 5a , O═NR 5a , O═PR 5a , O═AsR 5a , B, BR 5a , SiR 5a , SiR 5b R 5c , CR 5a , or CR 5b R 5c , where R 5b , R 5b , and R 5c each independently represents hydrogen, substituted or unsubstituted C 1 -C 4 alkyl, or substituted or unsubstituted aryl;
R 7a and R 7b each independently represents hydrogen, substituted or unsubstituted C 1 -C 4 alkyl, or substituted or unsubstituted aryl;
each R 3 , R 4 , R 5 , and R 6 independently represents hydrogen, halogen, hydroxy, amino, nitro, thiol, Si(C 1 -C 4 alkyl) 3 , substituted or unsubstituted C 1 -C 4 alkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted aryl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heteroaryl, or substituted or unsubstituted heterocycloalkyl; and
each of o, p, u, and v is an integer, valency permitting.
