Tunable construction of crystalline and shape-tailored Co3O4@TAPB-DMTP-COF composites for the enhancement of tert-butylhydroquinone electrocatalysis

Synthesis of pH-responsive covalent organic frameworks nanocarrier for plumbagin delivery

“…The high loading capacity of COF-366 for the encapsulation of PLB could occur for two reasons: (I) COF-366 is synthesized by organic linkers. So it is possible to interact with the PLB organic molecules through π–π stacking interaction; 30 (II) the relative high surface area of COF-366 could improve the adsorption capacity of PLB.…”

A highly sensitive electrochemical biosensor for the detection of hydroquinone based on a magnetic covalent organic framework and enzyme for signal amplification

“…This good stability can be attributed to the interlayer force between the components of the 2D layers. 18…”

“…This good stability can be attributed to the interlayer force between the components of the 2D layers. 18 The interferences of various substances on the proposed electrochemical enzymatic biosensor were evaluated by detecting a solution including 20 mmol L À1 hydroquinone and potential interfering species. For environmental water samples, Na + , K + , Ca 2+ , Zn 2+ , Cu 2+ , Fe 3+ , CH 3 COO À , NO 3 À , CO 3…”

“…As is well-known, covalent organic frameworks (COFs) are crystalline organic porous polymers whose ordered network structures are connected by robust covalent bonds. 17–19 In comparison with other porous materials, (I) the merit of porous structure endows COFs with high active specific surface area and tunable pore size; 20 (II) the ordered pore structure of COFs not only improves charge transport but also enhances the response speed of the biosensor; 21 (III) they also can surmount the disadvantages of irregular pore distribution and bad crystal form. In addition, the customizable functional groups of COFs can easily combine with enzymatic groups, which is conducive to modulating the biological activity of the enzyme.…”

Electrochemical (Bio)Sensors Based on Covalent Organic Frameworks (COFs)

“…Other examples of the combination of COF with a metal oxide nanomaterial is reported by Y. Chen et al [94]. A monomer-mediated in situ growth strategy is followed for the controllable construction of the core-shell Co 3 O 4 @TAPB-DMTP−COF composite using TAPB (1,3,5-tris(4-aminophenyl)benzene) and DMTP, (2,5-dimethoxyterephaldehyde) as precursors.…”
