I want to make a polymer by adding two polymeric substituent groups to azobenzene (I would like only N-azobenzene-N where N is a polymer and repeats). I have been reading about how they make the polymer. The synthetic methods are quite difficult and expensive.

I thought that azobenzene could be obtained as the result of the oxidation of aniline with potassium permanganate, and then see how to polymerize the azobenzene group as a substituent in a polymer already having the monomer.

The simplest synthesis I can find is using isocyanate oligomer 4-aminoazobenzene=azobenzene (1,4-diazabicyclo[2.2.2]octane) =DABCO (catalyst)

I do not understand almost anything about the reaction mechanism, and I'm looking for simpler ways to link a polymer chain to azobenzene.

  • $\begingroup$ @NilayGhosh I don't know if it's wrong but I think azobenzene polymers use a lot of solid state stuff, like for example inorganic catalysts and things like clousters are needed for some syntheses. $\endgroup$

  • $\begingroup$ Interesting that azobenzene may be conjugated and strictly hindered enough not to polymerize without adding in another monomer. $\endgroup$
