无长链席夫碱衍生物单分子膜和LB膜
Monolayers and Langmuir-Blodgett Films of Benzimidazole-containing Schiff Bases without Substituted Alkyl Chain
【摘要】 在银离子的诱导下 ,两种含有苯并咪唑、没有长链取代基的席夫碱衍生物可以形成稳定的单分子膜.此单分子膜可以用水平拉膜法转移到固体表面形成LB膜 ,LB膜的紫外吸收光谱和光电子能谱研究表明 ,Ag(I)离子被络合进了单分子膜中.
【Abstract】 Two benzimidazole containing Schiff bases 2 (2′ hydroxybenzylidene) aminobenzimi dazole (HBA) and 2 (2′ hydroxynaphthylidene) aminobenzimidazole (HNA),which have no substituted alkyl chains,have been found to form stable monolayers at the air/water interface in the presence of Ag(I) ion in the subphase. It has been found from UV vis spectra and XPS measurements that the complex formation between the Schiff bases with Ag(I) ion induced the monolayer formation.
