Poly(4\|vinyl phenol) (PVPh) was synthesized from anisaldehyde via Perkin Doebner and decarboxyl reactions to form 4 methoxy styrene.It was then polymerized by free radical polymerization following dealkylation to form PVPh.A kind of stable multilayer utra thin film was successfully fabricated via self assembly technique from PVPh and diazoresin (DR) followed by UV irradiation.The driving force of self assembly was confirmed to be the hydrogen bonding attraction from diazonium group(—N + 2)of DR a...
