| 中文摘要 | two orange phosphorescent iridium complex monomers, 9-hexyl-9-(iridium (iii)bis(2-(4'-fluorophenyl)-4-phenylquinoline-n, c-2')(tetradecanedionate-11,13))-2,7-dibromofluorene (br-pir) and 9-hexyl-9-(iridium(iii)bis(2-(4'-fluorophenyl)-4-methylquinoline-n, c-2')(tetradecanedionate-11,13))-2,7-dibromofluorene (br-mir), were successfully synthesized. the suzuki polycondensation of 2,7-bis(trimethylene boronate)-9,9-dioctylfluorene with 2,7-dibromo-9,9-dioetylfluorene and br-plr or br-mir afforded two series of copolymers, pirpfs and mirpfs, in good yields, in which the concentrations of the phosphorescent moieties were kept small (0.5-3 mol % feed ratio) to realize incomplete energy transfer. the photoluminescence (pl) of the copolymers showed blue- and orange-emission peaks. a white-light-emitting diode with a configuration of indium tin oxide/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/pir05pf (0.5 mol % feed ratio of br-pir)/ca/al exhibited a luminous efficiency of 4.49 cd/a and a power efficiency of 2.35 lm/w at 6.0 v with commission internationale de l'eclairage (cie) coordinates of (0.46, 0.33). the cie coordinates were improved to (0.34, 0.33) when copolymer mir10pf (1.0 mol % feed ratio of br-mir) was employed as the white-emissive layer. the strong orange emission in the electroluminescence spectra in comparison with pl for these kinds of polymers was attributed to the additional contribution of charge trapping in the phosphorescent dopants. |
