用“表面离子”法制备组分可控的LB膜超分子体系

综述了LB膜超分子体系中“表面离子”法的概念及其与传统的“亚相离子”法的区别. 分别以钌螯合物(Ru(ph2phen)32＋)和金属β-二酮螯合物为例,详细描述这两类不同的“表面离子”在水面上的成膜作用机理,并举例说明“表面离子”法在铺展膜和LB膜中,功能分子二维密度和凝聚态结构精确可调,并对“表面离子”法在多功能分子体系中的应用作了详细描述.

Fabricating Component-controlled LB films by Means of "Surface Ions" Technique

In this paper, we discussed the concept of “surface ions” and the differences between “surface ions”method and traditional “subphase ions” method. The “surface ions” method is a newly developed technology on functional Langmuir-Blodgett(LB) film fabrication and allows water-insoluble, non-amphiphilic functional molecules to be applied in fabricating LB films. Also we discussed the monolayer-formation mechanism of two different types of “surface ions”: Ru chelates and metal β-diketone complex. In the end, we introduced“surface ions” method’s application in the supramolecular systems. The components in Langmuir monolayer and LB films can be controlled and adjusted easily. “Surface ions” method can also be applied in multi-component functional molecular systems.
