The trace amount of water in organic solvents can affect the progress of chemical reactions, which will adversely affect chemical production in many industries, resulting in a doubling of costs. In this work, carbon dots (CDs) with abundant polar groups were synthesized by a simple one-step hydrothermal method. The prepared CDs showed superior dispersibility and fluorescence performance compared to the CDs that have been reported for the detection of water content in organic solvents. It can realize the fluorescence detection of trace water in several water-soluble organic solvents such as N,N-dimethylformamide, ethanol and methanol with wide linear range (0 %-100 %) and high sensitivity. This will provide a powerful tool for the rapid detection of water content in organic solvents in chemical production.
有机溶剂中的微量水分会影响化学反应进程，这将对许多行业的化学生产产生不利影响，导致成本翻倍。在这项工作中，通过简单的一步水热法合成了具有丰富极性基团的碳点（CDs）。与已报道的用于检测有机溶剂中水分含量的碳点相比，所制备的碳点表现出优异的分散性和荧光性能。它能够实现对N，N-二甲基甲酰胺、乙醇和甲醇等几种水溶性有机溶剂中微量水的荧光检测，具有宽线性范围（0%-100%）和高灵敏度。这将为化学生产中有机溶剂水分含量的快速检测提供有力工具。
