4-(2-(4′-(2,2-diphenylvinyl)biphenyl-4-yl)vinyl)-N,N-diphenylaniline derivatives for blue organic light-emitting diodes

This paper reports the synthesis and electroluminescent properties of the new blue fluorescent diphenylaniline derivatives end-caped with various aryl groups. Multilayered OLEDs were fabricated using these materials as dopants in ADN host, with the configuration of ITO/DNTPD (40 nm)/NPB (20 nm)/ADN: Blue dopants 1-4 (20 nm)/Alq3 (40 nm)/Liq (1.0 nm)/Al. All devices showed the efficient blue emissions. Among these devices, the devices C as a dopant exhibited blue emission with the luminance of 18020 cd/m2 at 11v, the luminous efficiency of 9.6 cd/A at 20 mA/cm2, the power efficiency of 3.91 lm/W at 20 mA/cm2. In addition, the device D exhibited deep blue emisson with CIE coordinates of (0.151, 0.134) at 8 V showed a luminous efficiency of 5.3 cd/A and power efficiency of 2.3 lm/W at 20 mA/cm2.

Highly efficient blue-light-emitting diodes based on styrylamine derivatives end-capped with a diphenylvinyl group

In this paper, we reported the synthesis and electroluminescent properties of blue fluorescent styrylamine derivatives end-capped with a diphenylvinyl group. A new series of styrylamine derivatives have been synthesized via the Horner- Wadsworth-Emmons reaction. To explore electroluminescent properties of these molecules, multilayer organic lightemitting devices with the configuration of ITO/NPB/1-5 doped in MADN/Bphen/Liq/Al were fabricated. All devices exhibited blue emissions with good EL performances. Among those reported herein, the device using dopant 5 exhibited a maximum luminance of 24,000 cd/m 2 at 11.0 V, a luminous efficiency of 12.5 cd/A at 20 mA/cm 2, a power efficiency of 6.50 lm/W at 20 mA/cm2, and CIEx,y coordinates of (x = 0.173, y = 0.306) at 8.0 V, all of which demonstrate the superiority of these materials in blue OLEDs.
