“…On the other hand, the comparison with metallic oxide composites demonstrate a superior performance with low detection limits under 0.25 μM in most cases, whereas metallic oxides presented high LODs, and null capability of detecting these analytes individually. 95 As summarized in Table I, COF-based sensors exhibit enhanced analytical parameters due to the conductivity properties of metallic nanomaterials and the redox properties inherent to certain COFs.…”

Covalent organic frameworks (COFs) have emerged as a ground-breaking class of porous crystalline materials, offering unparalleled potential in the realm of electrochemistry. Their exceptional properties, including high surface area, tunable porosity, chemical stability, and redox properties make COFs uniquely suited for advanced electrochemical sensors. This review delves into the main aspects of COFs, exploring their synthesis methods, intrinsic properties, and pivotal role in enhancing electrochemical sensor performance. Moreover, the latest advancements in COF-based electrochemical sensors will be discussed, highlighting their versatile applications in detecting a wide array of analytes such as biomolecules, metal ions, and organic pollutants. By summarizing the significant challenges and promising opportunities in this field, we underscore the transformative potential of COFs in electroanalytical chemistry and their seamless integration into next-generation electronic devices.

Two-dimensional (2D) metal oxides (2DMOs), such as MoO2, have made impressive strides in recent years, and their applicability in a number of fields such as electronic devices, optoelectronic devices and lasers has been demonstrated. However, 2DMOs present challenges in their synthesis using conventional methods due to their non-van der Waals nature. We report that KCl acts as a flux to prepare large-area 2DMOs with sub-millimeter scale. We systematically investigate the effects of temperature, homogeneous time and cooling rate on the products in the flux method, demonstrating that in this reaction a saturated homogenous solution is obtained upon the melting of the salt and precursor. Afterward, the cooling rate was adjusted to regulate the thickness of the target crystals, leading to the precipitation of 2D non-layered material from the supersaturated solution; by applying this method, the highly crystalline non-layered 2D MoO2 flakes with so far the largest lateral size of up to sub-millimeter scale (~ 464 μm) were yielded. Electrical studies have revealed that the 2D MoO2 features metallic properties, with an excellent sheet resistance as low as 99 Ω·square−1 at room temperature, and exhibits a property of charge density wave in the measurement of resistivity as a function of temperature.
