1,3-Dihydroimidazo[4,5-b]pyridin-2-ones and corresponding thiones have utility as analgesic, antipyretic and antiinflammatory agents. They are generally prepared by treatment of a 2,3-diaminopyridine with phosgene or thiosphosgene followed by further substitution if desired.
Organometallic compounds comprising an imidazole carbene ligand having a N-containing ring fused to the imidazole ring are provided. In particular, the N-containing ring fused to the imidazole ring may contain one nitrogen atom or more than one nitrogen atom. These compounds may demonstrate high photoluminescent (PL) efficiency, Gaussian emission spectra, and/or short excited state lifetimes. These materials may be especially useful as blue phosphorescent emitters.
