Position Effect Based on Anthracene Core for OLED Emitters

J Nanosci Nanotechnol. 2016 Mar;16(3):3045-8. doi: 10.1166/jnn.2016.11056.

Abstract

Green-orange emitters based on anthracene core have been successfully synthesized by substitution with triphenylamine side group in the 9, 10 or 2, 6 positions. There are larger blue shifts in the UV-visible absorption and PL spectra of the synthesized 2,6-substituted derivative compared to the 9,10-substituted derivative. When the synthesized compounds were used as emitting layers in non-doped OLED devices, a related trend was observed in their optical properties. In particular, the OLED device containing the 2,6-substituted derivative was found to exhibit excellent characteristics, with maximum EL emission at 518 nm, pure green emission with CIE coordinates of (0.334, 0.604), and external quantum efficiency of 2.83%.
