Covalent Organic Framework Composites: Synthesis and Analytical Applications

Abstract

In the recent years, composite materials containing covalent organic frameworks (COFs) have raised increasing interest for analytical applications. To date, various synthesis techniques have emerged that allow for the preparation of crystalline and porous COF composites with various materials. Herein, we summarize the most common methods used to gain access to crystalline COF composites with magnetic nanoparticles, other oxide materials, graphene and graphene oxide, and metal nanoparticles. Additionally, some examples of stainless steel, polymer, and metal-organic framework composites are presented. Thereafter, we discuss the use of these composites for chromatographic separation, environmental remediation, and sensing.

Computational investigation of a covalent triazine framework (CTF-0) as an efficient electrochemical sensor

“…18 CTFs have numerous active sites and large pp stacking, which make them exceptionally potential candidate to acquire some promising characteristics as imparted by graphitic carbon nitride or N-doped graphene surfaces. 19 These exceptional characteristics enable CTFs for a number of applications including photocatalysis, 20 solar cells, [25][26][27][28] energy storage, 29 degradation of organic pollutants, 30 heterogeneous catalysis, 31 and electrochemical sensors. [31][32][33][34][35] In electrochemical sensors, the use of CTFs has attained growing interest in recent years.…”

Chemistry of magnetic covalent organic frameworks (MagCOFs): from synthesis to separation applications

“…[6][7][8] COFs represent a promising class of well-defined porous and crystalline polymeric materials synthesized via condensation reactions of 2D and 3D organic building precursors. 9,10 In general, they are composed of light elements such as hydrogen, boron, oxygen, carbon, nitrogen and silicon which are linked via strong covalent bonds in a reversible manner to generate reticular architecture. This thermodynamically controlled and…”
