Synthesis, photophysical and electroluminescent properties of 1,3-diphenyl-1H-benzo[g]pyrazolo[3,4–b]quinoxaline

• 1,3-diphenyl-1H-benzo[g]pyrazolo[3,4-b]quinoxaline 7 has been synthesized.
• Absorption, photoluminescence and electroluminescence spectra of 1,3-diphenyl-1H-benzo[g]pyrazolo[3,4-b]quinoxaline 7 were measured.
• Fabrication of OLED based on a new azaacene derivative 7.
• Characteristics for OLED were measured.

Experimental investigations of electroluminescence spectra for new azaacene derivative have been performed. Azaacene was used as dopant in PVK matrices in electroluminescence devices with ITO/PEDOT:PSS/active layer/Ca/Al light-emitting diode configuration. The yellow emission was obtained with the electroluminance of 1530 cd/m2 at 15.0V.
