“…Some innovative approaches to improve the conductivity of COFs involves the development of composite materials that combine COFs with conducting polymers [84]. A core-shell material made of TAPB-DMTP-COF (TAPB, 1,3,5-tris(4-aminophenyl)benzene; DMTP, 2,5-dimethoxyterephaldehyde) core and a polyanyline-conducting polymer as shell, TAPB-DMTP-COF@PANI, is solvothermally synthesized.…”

“…Instead of using macrocycles, new set-ups are using molecularly imprinted polymers (MIP) as recognition elements together with the use of COFs and metal nanoparticles. A good example for the determination of sulfathiazole was described by Sun et al [84,102] using a molecularly imprinted polypyrrole film. AuNPs@COF with good electrical conductivity was introduced on the electrode surface for signal amplification and facilitation of the electron transfer processes of the redox probe employed, CuS.…”

Covalent organic frameworks (COFs) are defined as crystalline organic polymers with programmable topological architectures using properly predesigned building blocks precursors. Since the development of the first COF in 2005, many works are emerging using this kind of material for different applications, such as the development of electrochemical sensors and biosensors. COF shows superb characteristics, such as tuneable pore size and structure, permanent porosity, high surface area, thermal stability, and low density. Apart from these special properties, COF’s electrochemical behaviour can be modulated using electroactive building blocks. Furthermore, the great variety of functional groups that can be inserted in their structures makes them interesting materials to be conjugated with biological recognition elements, such as antibodies, enzymes, DNA probe, aptamer, etc. Moreover, the possibility of linking them with other special nanomaterials opens a wide range of possibilities to develop new electrochemical sensors and biosensors.

“…Covalent organic frameworks (COFs) are porous frameworks of pure structural units composed by light elements, such as C, N, and B, through covalent bonds. − These predefined nanomaterials are decorated with various groups and thus have high surface area and molecular-level design features, which are considered as excellent materials in powertrain systems. − Nevertheless, the extremely low conductivity of COFs seriously impedes their applications in energy storage equipment. − In addition, the nanocrystalline properties of COFs with defects or multiple grain boundaries seriously hinder the flow of electrons and may become an obstacle to the manufacture of free-standing flexible supercapacitors. , It is worth noting that there are some reports of improving the conductivity of COFs by compounding carbon (CNT, graphene, etc. ), − loading conductive polymers within the COF backbone, ,, or exfoliating to reduce the diffusion pathway. − Nevertheless, the conformation and layout of COF-based self-supporting films with outstanding conductivity is still an underdeveloped field that needs further exploration.…”

The porous structural backbone and redox-active of covalent organic frameworks can facilitate the evolution of energy storage equipment with high electrochemical performances. However, the application of covalent organic frameworks as supercapacitor electrode materials in advanced energy storage equipment has been hindered on account of the insufficient conductivity and consecutive impoverished electrochemical performances. Here we give an account of an efficacious method for improving the electrical conductivity of anthraquinonecontaining covalent organic frameworks (COFs) by incorporating reduced graphene oxide (rGO) sheets into the COF. Benefiting from the in situ synthesis of the COF along the surface of the twodimensional rGO nanosheets, the obtained COF@rGO hybrid films possess important intermolecular π−π interaction between rGO nanosheets and the COF. Meanwhile, the presence of the COF can avoid accumulation of rGO nanosheets, thereby achieving effective electrolyte ion transportation. Therefore, the optimal COF@rGO film possesses a good specific capacitance of 451.96 F g −1 , showing breakthrough within COF-based electrodes. In addition, the assembled planar COF@rGO microsupercapacitor (COF@ rGO-MSC) delivers a large stable electrochemical window (2.5 V), a good energy density (44.22 W h kg −1 ), and an excellent structural stability.

“…In recent years, COFs have been extensively used in numerous fields because of their large specific surface area, , low density, strong stability, , periodic and highly ordered pore structure, and easy functionalization. , These advantages endow COF materials with unique superiority in many applications. At present, COF materials have been used in gas adsorption and storage, , photoelectric fields, − catalytic organic reactions, , and clean energy and biological applications. − Although COFs have been applied for TNP detection, a focus are the development of new COFs materials and the sensitivity and selectivity of detection has not been studied in detail. ,, To the best of our knowledge, from previous reports, COFs can only achieve detection and not the purpose of removal. Therefore, it is especially necessary to develop simple and practical fluorescent COFs to realize simultaneous sensitive detection and efficient removal of TNP.…”

The detection and removal of 2,4,6-trinitrophenol (TNP) are extremely important because of the growing levels of pollution in the environment and water sources. In this paper, a multifunctional material based on Kadsura-shaped fluorescent covalent–organic framework (COF) nanostructures was developed and applied to the simultaneous sensitive detection and effective removal of TNP for the first time. Kadsura-shaped fluorescent COFs with stable nanostructures were obtained by a facile one-step synthesis strategy at normal temperature. It should be noted that TNP could prominently and rapidly quench the fluorescence of Kadsura-shaped COFs by the inner filter effect (IFE), with a detection limit of 1.7 nM and a linear range of 5.0 × 10–3–2.0 × 102 μM. The established method could be successfully employed for the analysis of TNP in a natural water environment. Moreover, a filter-paper-sensing element for the visual detection of TNP was also fabricated, which provided an effective and efficient visualization platform for TNP detection. Meanwhile, as an adsorbent, Kadsura-shaped COFs could effectively adsorb and remove TNP in the samples. The maximum saturated adsorption capacity of Kadsura-shaped COFs was 656 mg/g, which was the maximum reported thus far. The proposed approach could not only achieve fluorescence detection and visual analysis of TNP but also remove TNP in environmental samples, which provided a modest contribution to environmental protection.
