聚(对乙烯基苯酚)的合成及其与重氮树脂的氢键自组装研究

带相反电荷的聚电解质，交替沉积在基片，形成超薄有序膜，通常称为静电自组装，自1991年由Decher首次阐明以来，静电自组装技术引起了广泛重视，利用氢键相互作用的氢键自组装1997年才有报道，沈家骢、张希等从聚丙烯酸和聚乙烯基吡啶通过氢键组装了有序超薄膜。和乙烯基吡啶通过氢键组装超薄膜的制备。由于静电力和氢键均很弱，此类膜对极性溶剂不稳定，如在DMF中会离解而遭破坏，我们曾报道重氮树脂（DR）与酚醛树脂间通过氢键的自组装，本文报道聚（对乙烯基苯酚）（PVPh）的制备及春与重氮树脂（DR）间的氢键相经作用，并结合光照，制备了对极性溶剂稳定的超薄膜。

SYNTHESIS OF POLY(4-VINYL PHENOL)AND ITS SELF- ASSEMBLY WITH DIAZORESIN VIA H-BOND

Poly(4-vinyl phenol) (PVPh) was synthesized from anisaldehyde via Perkin-Doebner and decarboxyl reactions to form 4-methoxy styrene.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.
