Abstract
A new twisted polymer, poly[9,9ʹ-spirobifluoren-2,2ʹ-ylene-vinylene-alt-2,5-di(n-buthoxy)-1,4-phenylene-vinylene] (PSBF-PV), which consists of phenylenevinylene chromophores linked through 9,9ʹ-spirobifuorene, was synthesized through the Horner–Emons condensation. PSBF-PV showed strong green emission in solution and film. The single-layer light-emitting diode (LED) exhibited weak emission, and an improved performance with the maximum external quantum efficiency of 0.25% and luminance maxima of 1168 cd/m^2 was achieved using Alq3 as electron injection layer in double layer LED for PSBF-PV.
