摘　　要：The self assembly between diazoresin(DR) and the homopolymer or copolymers of 4 N hydroxyphenyl acrylamide(NHPA) has been investigated.It was confirmed that the driven force of the assembly is H bonding attraction, in which the DR plays a role of H acceptor, while the NHPA polymers act as a H donor, Under UV, the multiayer films become very stable towards polar solvents. For example, no any change was observed when the irradiated film was immersed in DMF at 20 ℃ for 12 h, but the unirradiated film was destroyled completely when it was immersed in DMF at the same temperature for 20 min. The dramatically improvement for the stability of the film towards polar solvents should be attributed to the bond conversion of the layers from H bond to covalent bond under UV irradiation.The self assembly between diazoresin(DR) and the homopolymer or copolymers of 4 N hydroxyphenyl acrylamide(NHPA) has been investigated.It was confirmed that the driven force of the assembly is H bonding attraction, in which the DR plays a role of H acceptor, while the NHPA polymers act as a H donor, Under UV, the multiayer films become very stable towards polar solvents.
