Redox Polymers as Chromophores

We are also interested in the polyphenelyene vinylene (PPV) family of polymers. Some of our recent work is based upon the following observations:

PPV molecules are "tunable" by small structural variations

PPV oligomers emit at different wavelengths for different molecular weights.

PPV's with kinked chains have different emission spectra than non-kinked chains

PPV's with kinked chains have enhanced solubility.

Therefor, we are constructing we are developing synthetic routes to to oligomers of PPV with well defined length and structure.

From here, a variety of polymers can be prepared. For example:
