  Investigating photoluminescence and electroluminescence of iridium(III)-based blue-emitting phosphors

  摘要：

  The syntheses of two new cyclometalated ligands [2-(2',4'-difluorophenyl)-4-tert-butylpyridine (F(2)(t)Buppy) and 2-(2',4'-difluorophenyl)-4-oxyhexylpyridine (F(2)HexOppy)] were carried out. Blue-light emitting iridium(III) complex dopants [Ir(F(2)Buppy)(2)(acac/pic)] (acac = acetylacetone; pic = picolinic acid) and [Ir(F(2)HeXOppy)(2)(acac/pic)] were prepared using these cyclometalated ligands with acetylacetone and picolinic acid as their ancillary ligands. The structure of the complexes, [Ir(F(2)(t)Buppy)(2)(acac)] and [Ir(F(2)(t)Buppy)(2)(pic)] were authenticated by X-ray single-crystal structure analysis and showed an octahedral geometry. Comparative absorption and emission spectra of thin-films as well as their solution samples were studied. The variation of the lowest emitting states to their corresponding unsubstituted complexes, [Ir(F(2)ppy)(2)(acac/pic)] was also discussed. The electroluminescent (EL) device was fabricated using [Ir(F(2)(t)Buppy)(2)(pic)] as the dopant (D-I) into the emitting layer and compared with two other EL devices where [Ir(F(2)MeOppy)(2)(acac)] (D-II) and FIrpic (D-III) dopants were used in the same device structure. The lower driving voltages obtained for D-I with respect to D-II and D-III devices were rationalized. The exceptional lowering of the luminance yield of the substituted dopants containing devices, D-I and D-II, to that of D-III which contains the unsubstituted dopant was also investigated.
