  title={Electrochemical Sensors Based on Covalent Organic Frameworks: A Critical Review},
  author={Si Chen and Baiqing Yuan and Gang Liu and Daojun Zhang},
  journal={Frontiers in Chemistry},
The metal-free cousins of metal-organic frameworks, covalent organic frameworks (COFs), are a class of pre-designable crystalline polymers composed of light elements and connected by strong covalent bonds. COFs are being given more and more attention in the electrochemical sensor field due to their fascinating properties, such as highly tunable porosity, intrinsic chemical and thermal stability, structural diversity, large specific surface area, and unique adsorption characteristics. However…
