Abstract
A conjugated light-emitting polymer based on the binaphthyl structure was s ynthesized via the Wittig-Horner condensation reaction. By introducing a tw isted, noncoplanar binaphthyl unit, it provides an effective approach for t ailoring the spectral characteristics and solubility of the polymer. The po lymer has a very high glass transition temperature (T-g) of 225 degrees C a nd good solubility in common organic solvents. A single layer light-emittin g diode with a configuration of(ITO/polymer/Al) showed a respectable extern al quantum efficiency of 0.1%.
