摘要：

Using a self-assembly technique, a type of photoactive multilayer film was successfully fabricated from diazoresin (DR) and poly(4-vinylphenol) (PVPh) followed by UV irradiation. The driving force of the self-assembly was confirmed to be the H-bonding interaction between the diazonium group (-N-2(+)) of DR and the phenolic hydroxy group (-Ph-OH) of PVPh. A linkage conversion from an H-bond to a covalent bond takes place following the decomposition of the -N-2(+) group when the multilayer film undergoes UV irradiation. As a result, the stability of the film towards etching by polar solvents increases dramatically.
