8 . A composition comprising a complex of the formula:

wherein:
M is platinum or palladium,
each of Ar 1 , Ar 2 , Ar 3 , and Ar 4 is independently a substituted or unsubstituted aromatic ring or heterocyclic group,
each of X 1 , X 2 , X 3 , and X 4 is independently a carbon or a nitrogen atom,
Ar 5 is an aromatic ring or a heterocyclic group,
Ar 6 is an aromatic ring, a heterocyclic group, or is absent,
A 1 is an optionally substituted nitrogen, carbon, boron, phosphorus, or silicon atom,
each of b 1 , b 2 , and b 3 is individually present or absent, and each b 1 , b 2 and b 3 present is independently an oxygen, sulfur, nitrogen, carbon, boron, phosphorus, or silicon atom.

9 . The composition of claim 8 , wherein

is isoquinolinyl, methylimidazolyl, or

is phenyl;

is pyridyl or phenyl;

is phenyl or pyridyl;

is: phenyl; and

is absent.

10 - 19 . (canceled)

20 . The composition of claim 8 , wherein the complex is represented by the structure:

21 - 23 . (canceled)

24 . The complex of claim 8 .
