文摘
- •
A novel light emitting material, NAMA, which contains anthracene as a main core unit and 3′,5′-diphenylphenyl group derivative as wings has been synthesized.
- •
NAMA exhibited promising high blue/near UV emission efficiency.
- •
This optimized device structure, is characterized by blue/near UV EL and a high current density with 7735 cd m−2 maximum brightness at approximately 10.4 V. Also the emitting color showed a blue/near UV emission (x, y) = (0.14, 0.10) at 277.1 mA cm−2 in CIE chromaticity coordinates with a long operational lifetime (180 h).
- •
We conclude that the blue/near UV emission is due to the intrinsic emission of NAMA's origin tile with a steady scaffold controlling the charge injection and transport properties.
