It was then polymerized by free-radical polymerization following dealkylation to form PVPh. A kind of stable multilayer utra-thin film was successfully fabricated via self-assembly technique from PVPh and diazoresin (DR) followed by UV irradiation. The driving force of self-assembly was confirmed to be the hydrogen bonding attraction from diazonium group(-N-2(+)) of DR and phenolic hydroxy group (-Ph-OH) of PVPh. The film becomes very stable towards polar solvents after UV irradiation and it is believed that the H-bonds between the layers of the film converts to covalent bonds following the decomposition of -N-2(+) groups when the multilayer film underwent UV irradiation.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000171044400031&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SCI(E)中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)502274-27
