Using the self assembly technique, a stable multilayer films was successfully fabricated from diazoresin (DR) and poly(styrene‐ co ‐( N ‐( p ‐hydroxyphenyl)maleimide)) (P(S‐ co ‐HPMI)) followed by UV irradiation. The driving force of the self‐assembly was confirmed to be H‐bonding attraction between the diazonium group (—N 2 + ) of DR and the phenolic hydroxy group (—Ph—OH) of P(S‐ co ‐HPMI). A linkage conversion from H‐bond to covalent bond takes place after decomposition of the —N 2 + group using UV irradiation. As a result, the stability of the film towards polar solvents increases dramatically.
