Photoluminescence and electroluminescence of 3-methyl-8-dimethylaminophenazine

A new phenazine dye—3-methyl-8-dimethylaminophenazine (MDAP) with intramolecular charge transfer (ICT) property was synthesized. The photoluminescence and electroluminescence of were investigated. The device with a configuration of ITO/TPD (30 nm)/TPD:MDAP (30 nm)/Alq3:MDAP (35 nm)/Alq3 (30 nm)/Mg:Ag (200 nm) showed a good performance with a brightness of 21650 cd/m2 at 250 mA/cm2, a maximum luminous efficiency of 9.97 cd/A and a yellow emission peaked at about 564–586 nm.
