We synthesized 6,13-Di-phenyl-pentacene (DPP), 6,13-Di-naphthalen-1-yl-pentacene (1-DNP) and 6,13-Di-naphthalen-2-yl-pentacene (2-DNP). Photoluminescent properties, electroluminescent properties and molecular interaction between 1-DNP and 2-DNP were discussed. EL spectra of synthetic materials showed similar tendency of EL maximum value at around 621/628 nm and 669/675nm. EL efficiency of Alq3 doped with 2-DNP also showed better efficiency of 0.67 cd/A and 0.13lm/W compared to DPP and 1-DNP’s due to different molecular interaction. |
