摘要: A series of anthracene-based conjugated copolymers containing 9,10-bis(6-bromonaphthalen-2- yl)-2-tert-butylanthracene (BNA) and 2,7-diphenyl substituted fluorene (DPPF) moieties are prepared via a palladium-catalyzed Suzuki polymerization. All of the synthesized polymers emit blue light at around 450nm and show good thermal and color stability. Their electro-luminescence spectra remain unchanged at high driving voltage. The double-layer polymer light-emitting diode (PLED) fabricated with ITO/PEDOT: PSS/DPPFBNA3/CsF/Al, produces a maximum brightness of 1 650 cd.m(-2) and has a luminance efficiency of 0.39 cd.A(-1). The ITO/PEDOT: PSS/TFB/DPPFBNA3/CsF/Al multilayer PLED, incorporating a TFB layer to facilitate hole transportation, produces a maximum brightness of 5 371 cd.m(-2) and a luminance efficiency of 1.18 cd.A(-1)
