  • Light-emitting fluorene-based copolymers, EL devices comprising the same and method of synthesis thereof
    Publication number: 20040166366
    Abstract: Light-emitting copolymers and electroluminescence products made therefrom emitting a wavelength range from that of blue light to that of red light. The light-emitting copolymers are represented by the following Formula 1, in which the energy of blue light emission from a fluorene repeating unit on a blue light-emitting fluorene-based main chain is transferred to a red comonomer in the copolymer to emit red light.

  • Blue light-emitting polymer and light-emitting diode adopting the same
    Patent number: 5731599
    Abstract: There are disclosed a blue light-emitting polymer and a light-emitting diode adopting the same. A conjugated polymer having phenylene residues substituted by a silicon-containing group in a main chain have blue light-emitting properties and a good solubility in organic solvent. Therefore, a light-emitting diode having an anode and a cathode on both sides of the conjugated polymer layer, respectively is capable of showing extended emission in the blue region and has an excellent light-emitting efficiency.
