摘要: An organic light emitting device is provided. The has an anode, a cathode, and emissive layer disposed between the anode cathode. further comprising material having structure: (I) M may be metal atomic weight greater than 40. R3 substituent Hammett value less about -0.17, -0.15 0.05, or 0.07. R5 H any substituent. A 5 6 member heteroaryl ring system. 'm' at least 1. 'n' zero. (X-Y) ancillary ligand. itself also have improved stability, provide saturated blue emission.
