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 degreesC 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.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000174163300048&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)202342-3442
