Preparation and diazo-coupling reaction of the pendant spacer-separated aniline residue based on a polyoxetane network

Polyoxetane networks anchoring the pendant spacer-separated aniline residue were prepared in good yield by a BF3-initiated ring-opening polymerization of the corresponding succinyl-protected oxetane monomer with a bisoxetane, as a crosslinking agent, followed by alkaline hydrolysis of the crosslinked product. Diazo-coupling reactions of the pendant aniline residue were examined with phenol and resorcinol, and the formation of desired polymers was confirmed by comparing the structures between the polymer products and the authentic polymers by IR and H-1-NMR spectroscopy.
