Emitting Color Controllable Polymers for Organic Light Emitting Diode Display Based on Partially Conjugated PPV Copolymers |
| abstract |
We disclose a new concept to realize emitter color control through the control of conjugation length of the partially conjugated poly(phenylenevinylene) (PCPPV) emitter using the conjugation limited atoms in their polymer backbone. Silicon, nitrogen, oxygen and sulfur are used as the conjugation limitation atoms. The emitting color of PCPPV depends on the conjugation length. For example, PCPPV with a short conjugation length can emit blue color. Increasing the conjugation length, the emitting color can change to longer spectral band such as green and red color. This new concept enables the color tuning for the realization of white light emitting polymer without any complicated fabrication process. The white light emitter can be realized via simple mixing of different color PCPPV emitters and can also be realized through random copolymerization of PCPPV with moderated monomer feeding ratios. |
