金属有机框架化合物薄膜是一类厚度从纳米到微米,物理或化学附着在(功能化的)基质上的多层材料.理想状况下,这类材料具有表面光滑并且同质性高的特点.各种各样新颖的方法被用于制备金属有机框架化合物薄膜材料.在这些先进的制备方法以及相应的薄膜材料中,由分步液相外延生长法制备的被称为表面金属有机框架化合物在研究和应用两个层面上都展现了极大的优势.这种制备方法是通过交替沉积金属和有机配体前驱体在功能化的表面上,最典型的就是包含巯基自组装单层.表面金属有机框架化合物结合了表面科学和表面金属有机框架化合物两个方面的优点.表面金属有机框架化合物具有其他方法制备的金属有机框架化合物所不具备的优点:(1)精确控制的厚度,表面粗糙程度,同质性还有生长取向;(2)研究金属有机框架化合物的生长机理;(3)在生长过程中调控它的结构从而调节它的性质;(4)以薄膜形式存在的金属有机框架化合物可以直接应用在传感器等领域.本综述聚焦分步液相外延生长法制备的表面金属有机框架化合物,基于本领域最新的进展讨论它的制备、生长机制、表征以及应用等方面.
Metal-organic framework compound films are a family of multi-layered materials that are physically or chemically attached to (functionalized) substrates from nanometers to microns in thickness, ideally with a smooth surface and high homogeneity. A variety of novel methods have been used to prepare metal organic framework compound thin film materials.In these advanced preparation methods and the corresponding thin film materials, by step liquid phase epitaxial growth method is called surface metal organic framework compounds in the study And application of the two layers have shown a great advantage.This preparation method is by alternating deposition of metal and organic ligand precursor on the functionalized surface, the most typical is the self-assembled monolayer containing mercaptans.Metal surface organic Framework compounds combine the advantages of surface science with surface-metal-organic framework compounds Surface-metal-organic framework compounds have the advantages that metal-organic framework compounds prepared by other processes do not have: (1) precisely controlled thickness, surface roughness, Homogeneity and growth orientation; (2) to study the growth mechanism of metal-organic framework compounds; (3) to adjust the growth process Its structure to regulate its properties; (4) the existence of thin-film metal organic framework compounds can be applied directly in the field of sensors and other fields.This review focuses on the preparation of surface-metal-organic framework compounds by step liquid phase epitaxy, based on the field Recent advances discuss its preparation, growth mechanism, characterization and applications.
