Electrochemiluminescence (ECL) is a light emitting phenomenon using excited luminophores induced by electrochemical redox reactions. In general, ruthenium(Ⅱ) (Ru(bpy)32+) and iridium(Ⅲ) (Ir(diFppy)2(ppy)+) complexes have been utilized as typical luminophores emitting red-orange- and green-colored light, respectively. In this work, to realize a wide variety of colors, another iridium(Ⅲ) complexe (Ir(ppy)2(bpy)+) showing yellow-orange color was synthesized by tuning the ligand structure, which was applied to ECL devices. Also, we successfully demonstrated remarkable luminance enhancement of yellow-orange-colored light by incorporating Ir(diFppy)2(ppy)+ as a coreactant. |
