摘　　要：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 and phenolic hydroxy group(—Ph—OH)of PVPh.The film becomes very stable towards polar solvents after UV irradiation and it is believed that the H bonds between the layers of the film converts to covalent bonds following the decomposition of —N + 2 groups when the multilayer film underwent UV irradiation.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 and phenolic hydroxy group (-Ph-OH) of PVPh. The film becomes very stable towards polar solvents after UV irradiation and it is believed that the H-bonds between the layers of the film converts to covalent bonds following the decomposition of -N-2(+) groups when the multilayer film underwent UV irradiation.
