Synthesis, structure, photo- and electroluminescent properties of bis{(4-methyl-N-[2-[(E)-2-pyridyliminomethyl]phenyl)]benzenesulfonamide}zinc(II)

The synthesis, structure and photo- and electroluminescent properties of Zn(II) complex of 4-methyl-N-[2-[(E)-pyridinylmethyl]phenyl]benzosulfimide are described. OLED device with this complex as light-emitting layer has been fabricated. The OLED generated luminance of more than 1000 cd/m2 at 16 V, current density 600 mA/cm2 and rather low turn-on voltage of ca. 4 V and power efficiency 1 lm/W.85
