Popis: | In this paper, we report the optical and electrical characteristics of organic electroluminescent diodes (OELDs) using phenylamine derivatives. The novel hetero-cyclic bis-styryl dyes, 2,2'-(1,4-phenylenedivinylene)bis-3,3'-dimethylindoline (PDV-DMI) and 2,2'-(1,4-phenylenedivinylene)bis-8-acetozyquinoline (PDV-AQ) were synthesized according to phase-transfer catalysis (PTC). The structure of fabricated OELDs was ITO anode/PEDOT/TPD/PDV-DMI or PDV-AQ/Al cathode. The brightness of the EL diodes with PDV-DMI or PDV-AQ had a maximum peak about 3700nW/cm 2 at 156mA/cm 2 and 6000nW/cm 2 at 130mA/cm 2 , respectively. The maximum EL peaks from PDV-DMI and PDV-AQ are at 615nm and 592nm which are corresponding to red and orange emission, respectively. The CIE coordinates of PDV-DMI and PDV-AQ are x =0.5635, y = 0.4277 and x = 0.4725, y = 0.4640, respectively. |
