摘要

用于化学电阻传感器的新型二维材料因其大表面积和结构多样性而极具吸引力。共价有机框架(COFs)因其独特的性能而备受关注,包括丰富的有机结构单元选择、永久性孔隙结构和结晶性,在复杂环境下的气体和湿度检测中显示出巨大的应用潜力。近年来,COFs 粉末和薄膜的合成和改性方法的发展有助于提高化学电阻传感器和集成器件的灵敏度和兼容性。本综述总结了当前 COFs 粉末和薄膜的合成方法及其在化学电阻传感器中的应用。为进一步开发 COFs 作为气体和湿度传感器中的活性材料,还讨论了当前的挑战和未来的改性策略。

Opportunity and Challenge of Emerging COFs in Chemiresistive Sensing for Gas and Humidity

Opportunity and Challenge of Emerging COFs in Chemiresistive Sensing for Gas and Humidity

Novel 2D materials for chemiresistive sensors are attractive due to their large surface area and structure diversity. Covalent organic frameworks (COFs) have received much attention due to their unique properties, including the abundant choice of organic building units, permanent pore structure and crystallinity, which show huge potential of implement in gas and humidity detection in complex environment. Recently, the development of the synthesis and modification methods for COFs powder and film contributes to the sensitivity and compatibility in chemiresistive sensors and integrated devices. In the present review, the current synthesis methods of COFs powder and film as well as their application in the chemiresistive sensors are summarized. The current challenge and future modification strategy are discussed for the further development of COFs as active materials in gas and humidity sensors.
