A new blue light-emitting material

We have prepared a novel thermally stable azomethin–zinc complex N,N′-disalicylidene-triethylenetetramine zinc(II) (1AZM-TEEA). Its optical, photoluminescence and electrical properties are reported and discussed. 1AZM-TEEA exhibits high thermal stability and good thin film forming ability, and shows bright blue photoluminescence. Light-emitting diodes using 1AZM-TEEA as the emissive layer emit blue light with a peak wavelength at 455 nm and a brightness of about 37.2 cd m−2.
