“…In comparison to SPME and chromatography, COF-based electrochemical sensors have higher sensitivity, and in comparison to luminescent and colorimetric sensing, The working electrode plays an important role in the qualitative and quantitative detection performance of the sensor. Many advanced materials have been applied to prepare the working electrodes of electrochemical sensors, mainly including graphene, 64 carbon nanotubes (CNTs), 65 quantum dots (QDs), 66 metal nanoparticles (NPs), 67 metal oxides, 68 conductive polymers (CPs), 69 biomolecules, 70 enzyme, 71 black phosphorus, 72 Mxene, 73 polyoxometalates (POMs), 74 Perovskite, 75 MOFs, 76 COFs, 77 and so on. Compared with other materials, COFs possess excellent structural diversity, enabling them to be fine-tuned to meet specific sensing requirements.…”

As an emerging porous crystalline organic material, the covalent organic frameworks (COFs) are given more and more attention in many fields, such as gas storage and separation, catalysis, energy storage and conversion, luminescent devices, drug delivery, pollutant adsorption and removal, analysis and detection due to their special advantages of high crystallinity, flexible designability, controllable porosities and topologies, intrinsic chemical and thermal stability. In recent years, the COFs are applied in analytical chemistry, for instance, chromatography, solid-phase microextraction, luminescent and colorimetric sensing, surface-enhanced Raman scattering and electroanalytical chemistry. The COFs decorated electrodes show high performance for detecting trace substances with remarkable selectivity and sensitivity, such as heavy metal ions, glucose, hydrogen peroxide, drugs, antibiotics, explosives, phenolic compounds, pesticides, disease metabolites and so on. This review mainly summarized the application of COF based electrochemical sensor according to different target analytes.

An electrochemical sensor for dopamine was developed by electrodepositing poly(propylene imine) (PPI) dendrimer and gold nanoparticles (AuNPs) onto a glassy carbon electrode (GCE). Electrochemical characterisation of the sensor was carried out by cyclic voltammetry and electrochemical impedance spectroscopy in ferri/ferrocyanide electrolyte. The nanocomposite elec-trode (GCE-PPI-AuNPs) showed improved electroactive surface area and electrochemical response over bare GCE. The sensor recorded a detection limit of 0.16 μM over a concentration range of 0.1 μM to 125 μM. The sensor was applied for dopamine detection in human serum samples and in the presence of interfering substances such as ascorbic acid and epinephrine.
