Stable self-assembled multilayer films of diazo resin and poly(maleic anhydride-co-styrene) based on charge-transfer interaction

Diazo resin (DR) and poly(maleic anhydride-co-styrene) (PMS) can form a charge-transfer complex in methanol. A multilayer film was fabricated successfully from DR and PMS based on the charge-transfer interaction. After UV irradiation, the stability of the film toward polar solvents increases significantly due to the formation of covalent bonds between DR and PMS.
