Abstract
ABSTRACTFour new diazocine derivatives including anthracene moiety, 2,8-Bis-[3-(10-naphthalen-2-yl-anthracen-9-yl)-phenyl]-6H,12H-5, 11-methano-dibenzo[b,f][1,5]diazocine(AK14), 2,8-Bis-[2-(10-naphthalen-2-yl-anthrac-en-9-yl)-phenyl]-6H,12H-5,11-methano-dibenzo[b,f][1,5]diazocine(AK15), 2,8-Bis-[4-(10-phenyl-anthracen-9-yl)-phenyl]-6H,12H-5,11-methano-dib-enzo[b,f][1,5]diazocine(AK20), 2,8-Bis-[2-(10-phenyl-anthracen-9-yl)-ph-enyl]-6H,12H-5,11-methano-dibenzo[b,f][1,5]diazocine(AK21) were synth-esized. Those materials exhibited photoluminescence (PL) maximum value of about 411∼428 nm in solution state and 429∼483 nm in film state, respectively.Four compounds were used as EML in OLED device: ITO / 2-TNATA (60 nm) / NPB (15 nm) / EML (35 nm) / Alq3 (20 nm) / LiF / Al. OLED devices, fabricated by AK14, AK20 and AK21, showed the current efficiency with 2.16cd/A, 0.28cd/A and 1.56cd/A. The OLED device, fabricated by AK15, showed the best performance with 2.83cd/A, 1.25lm/W and CIE(x,y) = (0.16, 0.23).
