Abstract :
The synthesis and photophysical properties of the robust Pt(II) emitters [(O N N)PtX] (HO N N = 6-(2-hydroxyphenyl)-2,2ʹ-bipyridine and its derivatives; X = Cl, Br, I, or -C(IDENTICAL)C-Ph) are reported. Yellow electroluminescent devices based on these materials display a low turn-on voltage (1 cd m^-2 at 4 V) and a high luminance (37000 cd m-2). Complex 2e, [(FtBu2O N N)PtCl], has the highest thermal stability and gave the best OLED.
