Colour tuning from green to red by substituent effects in phosphorescent tris-cyclometalated iridium(iii) complexes of carbazole-based ligands: synthetic, photophysical, computational and high efficiency OLED studies†
Abstract
Two series of fac-tris-cyclometalated iridium(III) complexes, series 1 from the 2-(carbazol-3′-yl)-pyridine
