随着人们对以石墨烯为代表的二维(2D)纳米材料不断深入与扩展研究,近些年来,以2D金属有机骨架(metalorganic frameworks,MOFs)和共价有机骨架(covalent organic frameworks,COFs)为代表的2D骨架材料引起了人们浓厚的研究兴趣和广泛关注.与其它的中孔或微孔的纳米材料相比,这些有机骨架材料提供了均一的纳米尺寸的孔,并且相较于石墨烯,2D有机骨架材料可以预期性地设计和组装功能化的结构单元,如羧基、氨基、羟基等基团可以通过多样的化学反应人为可控地接枝到骨架上,这些优点有望使2D有机骨架材料成为新一代提高传感界面灵敏度和稳定性的功能材料.本篇综述分别对2D MOFs和COFs进行简单的概述,总结目前以“自下而上”和“自上而下”两种制备2D MOFs和COFs纳米材料的方法并对其做出简单的点评,介绍(2D)MOFs和COFs材料在化学传感和生物传感方面的应用,讨论了2D MOFs和COFs在传感应用中的潜质和关键性问题,并对未来2D MOFs和COFs的应用前景做出了展望.
In recent years, with the development of 2D metal organic frameworks (MOFs) and covalent organic frameworks (COFs), as 2D nanostructured materials represented by graphene have been further studied, Has attracted much research interest and widespread attention as a representative 2D framework material.These organic framework materials provide uniform nano-sized pores in comparison with other mesoporous or microporous nanomaterials, , 2D organic framework materials can be expected to design and assembly of functionalized structural units such as carboxyl, amino, hydroxyl and other groups can be controlled by a variety of chemical reactions grafted onto the skeleton, these advantages are expected to make 2D organic framework Materials become a new generation of functional materials that improve the sensitivity and stability of the sensing interface.This review provides a brief overview of 2D MOFs and COFs, respectively, and concludes that “bottom-up” and “top-down” Two methods to prepare 2D MOFs and COFs nanomaterials were briefly reviewed. The applications of (2D) MOFs and COFs materials in chemical sensing and biosensing were introduced. The effects of 2D MOFs and COFs on Sense of the potential applications and the key issues, and the future prospects 2D MOFs and COFs made outlook.
