제목 High Efficiency Anthracene emitter based on Optimized Side Groups for green emission
초록 ​Two green fluorescent materials, N,N,N',N'-Tetra-o-tolyl-anthracene-9,10-diamine (o-Me-TAD) and N,N'-bis(2,5-dimethylphenyl)-N,N'-di-o-tolylanthracene-9,10-diamine (DMe-o-Me-TAD) including anthracene and diphenylamine moiety, were synthesized by Buchwald-Hartwig amination. In solution state, PL maximum wavelength of o-Me-TAD and DMe-o-Me-TAD is 518 nm and 520 nm. The doped device using o-Me-TAD as green fluorescent dopant exhibited CE of 19.78 cd/A and EQE of 5.97%. The doped device using DMe-o-Me-TAD as dopant exhibited CE of 22.37 cd/A and EQE of 7.02% without roll-off. Doped devices fabricated using o-Me-TAD and DMe-o-Me-TAD show the EL peaks at 522 and 523 nm corresponding to the Commission Internationale de L’Eclairage (CIE) coordinates of (0.29, 0.63) and (0.27, 0.61).
