AbstractWe report the properties of a binaphthyl-bithiophene copolymer (PHBNT2) used either as an emitter or as a hole transporter in light-emitting diodes. The polymer has a well-defined conjugation length between tow binaphthyl units that is independent of its polymer chain length. It is easily soluble in common organic solvents and can form high quality thin films by a spin coating technique. The HOMO and LUMO energy levels of the PHBNT2 were -5.42 and -2.50 eV respectively, as determined by cyclic voltammetry. A single layer device of ITO/PHBNT2/Al using PHBNT2 as an emitter, had a turn-on voltage of 5.7 V and had an orange emission peak at 568 nm. The luminous efficiency for a double-layer device of ITO/PHBNT2/Alq(3)/Al using PHBNT2 as the hole transporting layer is 0.57 lm . W-1.
