An oxidative homocoupling method of synthesizing certain 2,2′-bithiophenes from thiophenes using oxygen as the terminal oxidant is disclosed. In non-limiting examples, the method uses oxygen along with a catalytic system that includes palladium, an assistive ligand, and a non-palladium metal additive to catalyze one of the following reactions:
Associated catalytic systems and compositions are also disclosed.

The present invention relates to light emitting materials comprising novel ortho-metalated transition metal complexes [ĈN]
2
M[N̂N] comprising two orthometalated ligands (ĈN ligands) and a neutral bidentate bipyridine ligand (N̂N). Surprisingly, it has been found that when the metal binds both orthometalated chelate ĈN ligands and a neutral bidentate bipyridine ligand (N̂N), these ligands participate in the emission process, thus greatly improving the red emission efficiency of complexes [ĈN]

M[N̂N]. The present invention further relates to the use of such light emitting materials and an organic light emitting device comprising such light emitting material.
