4-Methylpicolinonitrile (cas: 1620-76-4) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Name: 4-Methylpicolinonitrile

Blue phosphorescent bipyridine-based iridium(III) complex for vacuum-deposited organic light-emitting diodes was written by Jang, Jae-Ho;Park, Jeong Yong;Un Kim, Hee;Park, Hea Jung;Kang, In-Nam;Lee, Jun Yeob;Hwang, Do-Hoon. And the article was included in Journal of Nanoscience and Nanotechnology in 2018.Name: 4-Methylpicolinonitrile This article mentions the following:

We have synthesized and characterized a blue phosphorescent iridium(III) complex (dfpypy)2Ir(tftamp), which contains 2′,6′-difluoro-2,3′-bipyridine (dfpypy) as the main ligand and 4-methyl-2-(3′-trifluoromethyl-1’H-1′,2′,4′-triazol-5′-yl)pyridine (tftamp) as the ancillary ligand. The photophys., electrochem., and electroluminescent (EL) properties of (dfpypy)2Ir(tftamp) were investigated. Vacuum-deposited blue and white organic light-emitting diodes (OLEDs) were fabricated using (dfpypy)2Ir(tftamp) in 1,3-bis(carbazol-9-yl)benzene (mCP) as the emitting layer. The EL spectrum of (dfpypy)2Ir(tftamp) exhibited emission maximum at 472 nm with a full-width at half-maximum (FWHM) of 81 nm and Commission Internationale de L’Eclairage (CIE) coordinates of (0.17, 0.27) at 100 cd· m-2. In addition, white-light-emitting devices were fabricated, which exhibited CIE coordinates of (0.42, 0.40) and a correlated color temperature (CCT) of 3,237 K at 1000 cd · m-2, close to the standard warm-white light CIE coordinates of (0.44, 0.40) and CCT of 3,000 K. In the experiment, the researchers used many compounds, for example, 4-Methylpicolinonitrile (cas: 1620-76-4Name: 4-Methylpicolinonitrile).
