Alkoxyphenyl-substituted polyfluorene: a stable blue-light-emitting polymer with good solution processability.
A new alkoxyphenyl-substituted poly(fluorene) was synthesized to suppress the emission of long-wavelength radiation. The polymer emitted pure blue light, the characteristics of which did not change upon thermal annealing or normal operation of the EL device.
