Abstract
Partially conjugated PPV derivatives as an emitting material were prepared in order to control the emitting color. According to the control of the conjugation length of the PPV emitters by using the conjugation interrupt atoms such as nitrogen (N-PPV) or silicon (Si-PPV) in their polymer backbone, various emitting PPV derivatives have been obtained. Highly efficient bright white emitter can be realized through simple mixing of various PPV derivatives.
