چکیده انگلیسی


• We synthesized the fluorescent materials based on arylamine substituted anthracene.
• These materials showed efficient blue and greenish-blue electroluminescence.
• These materials have appropriate potentials for applications in fluorescent OLEDs.

This paper reports synthesis and electroluminescent properties of the tert-butylated arylamine-substituted 9,10-diphenylanthracene derivatives for organic light-emitting diodes. The devices using these materials were fabricated in the following sequence: indium-tin-oxide/N,N'-di(1-naphthyl)-N,N'-diphenyl-(1,1′-biphenyl)-4,4′-diamine/emitting material/bathophenanthroline/lithium quinolate/aluminum. All devices showed the efficient electroluminescence depending on the photoluminescent properties of emitters. In particular, a device using 2-tert-butyl-9-(9,10-diphenylanthracen-2-yl)-9H-carbazole exhibited blue emission with the maximum luminance, luminous efficiency, power efficiency and external quantum efficiency of 2552 cd/m2, 2.14 cd/A, 1.17 lm/W and 2.04% at 20 mA/cm2, respectively, and Commission Internationale d′Éclairage (CIE) coordinates of (0.15, 0.12) at 6.0 V. These results suggest that the degree of self-aggregation of the emitters and charge-balances in the emitting layers of devices would be important roles in electroluminescent properties of devices.
