Langmuir膜及LB膜中的金属参与

本文主要介绍了金属离子与Langmuir膜及LB膜相互作用中静电、配位等作用方式及其对膜相态和分子二维排列的影响。在此基础上探讨了Langmuir膜对金属离子的识别与传感。以Langmuir膜和LB膜为二维模板诱导无机盐定向生长作为金属/单分子膜结合的重要应用在文中也进行了讨论。通过举例展示了金属离子参与的Langmuir膜和LB膜催化有机反应的特点。最后对金属参与的Langmuir膜和LB膜在功能化和器件化等方面的研究也作了论述， 并通过介绍金属螯合类脂分子的Langmuir膜在蛋白质等生物大分子界面定向聚集研究中的应用表明了金属参与的Langmuir膜及LB 膜在生命科学研究中的意义。全文贯穿了金属结合调节Langmuir膜和LB膜组装结构以及通过金属结合导入功能基团进行有序组装的思想。

Metal-incorporated Langmuir Monolayers and Langmuir-Blodgett Films

The electrostatic binding and metal coordination between metal ions and Langmuir monolayers or LB films are discussed, and their effects on the monolayer 2D structure and related phase behavior are analyzed. The interfacial recognition and sensing for metal ions by Langmuir monolayers are also shown. Langmuir monolayers and LB films as 2D template to induce the 2D-oriented crystal growth via metal/monolayer binding is especially demonstrated. The abnormal catalytic characteristics, the functions and devices of metal-incorporated Langmuir monolayers and LB films are displayed by some examples. The review also shows the application of metal-chelating lipid monolayers on the interfacial study of bio-macromolecules. The review suggests the great roles of metal/monolayer binding in alternating monolayer structures and the assembly of functional metal complexes.
