传统上，空气-水界面被用于制备粒子组件和金属和半导体薄膜。然而，水和有机液体之间的界面还没有得到充分的研究，因此可能用于制备纳米晶体和材料薄膜。在这篇文章中，我们展示了使用液-液界面作为介质来制备金属、硫族化合物和氧化物的超薄膜。该方法涉及在有机层中的金属有机化合物与水层中用于还原、硫化等的适当试剂之间的界面处发生反应。讨论的一些材料是在液-液界面形成的金、Cu、CuSe、CuO和Cu(OH)(2)的纳米晶膜。本文所报道的结果将证明液-液界面在制备纳米和超薄膜方面的多功能性和潜力，并鼓励这一领域的进一步研究。(c) 2005爱思唯尔公司版权所有。
The air-water interface has traditionally been employed to prepare particle assemblies and films of metals and semiconductors. The interface between water and an organic liquid, however, has not been investigated sufficiently for possible use in preparing nanocrystals and thin films of materials. In this article, we demonstrate the use of the liquid-liquid interface as a medium for preparing ultrathin films of metals, chalcogenides and oxides. The method involves the reaction at the interface between a metal-organic compound in the organic layer and an appropriate reagent for reduction, sulfidation, etc. in the aqueous layer. Some of the materials discussed are nanocrystalline films of gold, CuS, CuSe, CuO, and Cu(OH)(2) formed at the liquid-liquid interface. The results reported in this article should demonstrate the versatility and potential of the liquid-liquid interface for preparing nanomaterials and ultrathin films and encourage further research in this area.
