As a newly emerging kind of porous material, covalent organic frameworks (COFs) have drawn much attention because of their fascinating structural features (e.g., divinable structure, adjustable porosity and total organic backbone). Since the seminal work of Yaghi and co-workers reported in 2005, the COF materials have shown superior potential in diverse applications, such as gas storage, adsorption, optoelectronics, catalysis, etc. Recently, COF materials have shown a new trend in sensing fields. This critical review briefly describes the synthesis routes for COF powders and thin films. What's more, the most fascinating and significant applications of COFs in sensing fields including explosive sensing, humidity sensing, pH detection, biosensing, gas sensing, metal ion sensing, and other substance sensing are summarized and highlighted. Finally, the major challenges and future trends of COFs with respect to their preparation and sensing applications are discussed.
作为一种新兴的多孔材料,共价有机框架(COFs)因其引人注目的结构特征(如可预测的结构、可调节的孔隙率和全有机骨架)而受到广泛关注。自 2005 年 Yaghi 及其同事的开创性工作以来,COF 材料在气体存储、吸附、光电、催化等多种应用中显示出了优异的潜力。最近,COF 材料在传感领域显示出了新的趋势。本综述简要描述了 COF 粉末和薄膜的合成路线。更重要的是,总结并强调了 COFs 在传感领域包括爆炸物传感、湿度传感、pH 值检测、生物传感、气体传感、金属离子传感和其他物质传感方面最引人入胜和最重要的应用。最后,讨论了 COFs 在制备和传感应用方面的主要挑战和未来趋势。
