A new compound, 5-(9-anthryl)-1,3-diphenyl-1H-pyrazol (ADPP), with an anthryl moiety as an emissive groupand a diphenylpyrazoline moiety as a charge transporting group is designed and synthesized. The absorption,photoluminescence, electroluminescence, and electrochemistry are measured. Absorption of ADPP is similar tothat of anthracene in the vibonic structure but shows slight redshifts because anthryl moiety twists strongly withrespect to pyrazol moiety although delocalization still exists between the two moieties. Light-emitting devicesfabricated with ADPP show a bright blue emission at 470nm. The tu-on voltage is 12 V and the light emissionfollows the current closely, indicating an efficient charge injection and transport for both electrons and holes.
