Synthesis and electroluminescent properties of diazocine derivatives
Four 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 approximate to 428nm in solution state and 429 approximate to 483nm in film state, respectively.Four compounds were used as EML in OLED device: ITO / 2-TNATA (60nm) / NPB (15nm) / EML (35nm) / Alq3 (20nm) / 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).
