Dear All,
I want to graft PBA (Phenyl boronic acid) with some polymer having pendant hydroxyl groups. From Previous literature and my own observation, boronic acid forms a complex with these polyols and forms a gel. I want to fabricate a gel system through chemical crosslinking at the end by adding a crosslinker, but i get a gel due to this complex prior to chemical crosslinking. Could somebody please suggest or share his experience that how can this complex formation b/w boronic and hydroxyls be overcomed?
Kind Regards
Check your original post of this question - the use of diol protecting goups is suggested.

you can protect the diol by carboyl group, and you can also protect the PBA pinacol. the later one is always supplied commercially.
