organic light emitting device used as a dopant in the emission -bis ( triazine days) meten boron complexes

摘要

The present invention includes a complex system of five or more fused ring having one of the formulas 2 and 3 on one or more ring carbon or nitrogen, & lt solvent of ethyl acetate; 10 ^-3 as measured at a concentration of M, 520 emission bis substituent having sufficient to provide the maximum emission wavelength of less than (triazine days) an OLED device comprising a light-emitting layer containing boron complexes meten starts: ; Formula 2 ; Formula 3 ; wherein, ; Each of Xa, Xb, Xc and Xd is an independently selected substituent, two of which can be combined to form a fused ring and may include an additional fused ring optionally substituted; m and n are independently 0 to 2; o and p are independently 0 to 4; Y is H or value hwanche Za and Zb are independently selected substituents.
