Synthetic Route of 2516-40-7, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.2516-40-7, Name is 2-Bromobenzothiazole, molecular formula is C7H4BrNS. In a patent, introducing its new discovery.
N?C?N cyclometalated iridium(III) acetylide complexes in the 3 + 2+1 ligand mode were obtained and characterized. Cyclometalating ligands were bis(pyridyl)phenyl, bis(benzothiazolyl)phenyl and 2-phenylpyridine derivatives, while acetylene ligands represented 2-ethynylfluorene and 3-ethynylcarbazole derivatives. The HOMOs of the ethynyl iridium complexes are located on the ethynyl ligand and the iridium atom, whereas the LUMO is located exclusively on the N?C?N-cyclometalating ligand. All compounds showed phosphorescent properties, where the change of ligands significantly affects the wavelength of emission. Acetylide complexes emit light from the blue (? 400 nm) to orange (? 560 nm) range. Emission occurs from the mixed state 3MLCT/3LC, with a predominance of junction depending on the structure of the ligands.
