LIGHT-EMITTING FLUORENE-BASED COPOLYMERS, EL DEVICES COMPRISING THE SAME AND METHOD OF SYNTHESIS THEREOF.

摘要

Disclosed is a light-emitting copolymer having a wavelength range of emitting not only blue light but also red light, as 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. An electroluminescence device using the light-emitting copolymer is also disclosed.
