摘要:

金属-有机框架(MOFs)作为一种无机-有机杂化材料,由于其结构的多样性和独特的功能而在众多领域有着潜在的应用价值。尤其是液相外延层层组装的MOFs薄膜(称为表面配位MOFs薄膜,SURMOFs)因其具有可控的厚度、优选的生长取向以及均匀的表面等优点备受关注。本文总结了液相外延(LPE)层层组装MOFs薄膜的技术方法,如层层浸渍法、层层泵式法、层层喷雾法、层层旋涂法等组装方法,并介绍了经典的SURMOF HKUST-1的层层组装策略以及其在光致发光、光致变色、光催化以及电催化方面的相关应用。HKUST-1是经典的SURMOF材料之一,在光电领域具有广泛的应用,SURMOF HKUST-1具有以下独特的性能:可以作为发光载体实现良好的光学性能;具有独特的Cu催化活性位点的优势,有效地降解水中的污染物;因其具有介电特性而在电子器件方面有着潜在的应用。虽然HKUST-1在许多方面均具有独特的性能,但也面临着一些挑战:需要将薄膜的合成步骤简单化;薄膜结构和电催化行为间的机理也需要进一步的研究;降低HKUST-1的内阻的方法也需要进行改进。SURMOFs在大规模工业应用和扩展到其它未探索的领域还任重道远。

Abstract:

Metal-organic frameworks (MOFs) as a kind of inorganic-organic hybrid materials have potential applications in many fields due to their diverse structures and unique functionalities. In particular, liquid phase epitaxial layered MOFs films (called SURMOFs films, SURMOFs) have attracted much attention due to their controllable thickness, optimal growth orientation and uniform surface. This article summarizes the liquid phase epitaxy (LPE) layers of assembly MOFs thin film technology and methods, such as layer-by-layer (LBL) dipping method, LBL pump method, layer spray method and LBL spin coating method. The article also introduces the classical SURMOF layers of HKUST-1 assembly strategy and its related applications in photoluminescence, photochromic, photocatalytic and electrocatalysis. As one of the classical MOF materials, HKUST-1 has a wide range of applications in photoelectric field, and it has the unique properties: it can be used as a luminous carrier to achieve good optical properties; it has the advantage of unique Cu catalytic active site and can effectively degrade pollutants; it has potential applications in electronic devices because of its dielectric properties. Since SURMOF HKUST-1 has unique properties in many fields, it also faces some challenges: it needs to simplify the process of film synthesis; the structure of thin films and the mechanism of electrocatalysis also need further study; methods for reducing HKUST-1 internal resistance which can increase the conductivity also need to be improved. SURMOFs still has a long way to go for large-scale industrial applications and expansion to other unexplored areas.
