Abstract: 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.

Key words: Monolayer, LB films, “Surface ions”, Supramolecule
