Dear Sanjida,

sorry to see that your very interesting technical question has not yet received an expert answer. OPPy (= overoxidized polypyrrole) plays an important role in the manufacture of MIPs. The overoxidation of polypyrrole has been studied in detail in the following pioneering work:

Studies of the overoxidation of polypyrrole

Article Studies of the overoxidation of polypyrrole

Unfortunately the paper is not available as public full text on RG, but one of the authors has an RG profile (https://www.researchgate.net/profile/Gordon-Wallace). It is certainly worth a try requesting the full text directly from this author.

Also please search the "Publications" section of RG for the term "overoxidized polypyrrole" to find and access a number of other potentially useful literature references:

For example. the following interesting article is freely available as public full text on RG:

I hope this helps. Good luck with your research work and best wishes, Frank Edelmann

Thanks Prof. Edelmann
