Recent development of covalent organic frameworks (COFs): synthesis and catalytic (organic-electro-photo) applications

Abstract

The review focuses on recent developments in the synthetic methodologies of COFs and their applications in the field of organocatalysis, electrocatalysis and photocatalysis. Future scope of COFs in the field are also described.

Towards the room-temperature synthesis of covalent organic frameworks: a mini-review

“…In the meantime, chemists have shown great interest in the synthesis of porous and crystalline structures using chemistry science [1,2]. Porous and crystalline materials have ordered structure and also have separate molecular space which can interact with other molecules [3,4]. In this regard, Yaghi et al introduced porous and crystalline materials, namely covalent organic frameworks (COFs) for the first time in 2005, which were formed based on the condensation reaction between two-dimensional (2D) and three-dimensional (3D) organic building monomers [5,6].…”

“…COFs contain elements like H, B, C, N, and O which are connected together by covalent interactions (Fig. 1) [3]. COFs have designable and controllable structures that introduce them as porous materials.…”

Green Synthesized AgNPs Embedded in COF: An Efficient Catalyst for the Synthesis of 2‐Oxazolidinones and α‐Alkylidene Cyclic Carbonates via CO2 Fixation

“…Due to their interesting properties like large surface area, high chemical stability, structural versatility, and effortless surface modification, COFs are being widely utilized in catalytic, adsorption, sensing, gas storage and other numerous valuable applications. [29] On the other hand, metal nanoparticles fabrication has achieved a lot of attention in the nanotechnology field. Due to their unambiguous properties such as morphology, size, and distribution, nanoparticle displays entirely novel or superior properties and also creates an impact on various aspects of humanity.…”

Recent Bio-Advances in Metal-Organic Frameworks

“…Chedid and Yassin explored recent examples of the use of MOFs and covalent organic frameworks (COFs) for biomedical applications, focusing on their synthesis and use as DDS [23]. Similar to MOFs, COFs have been used for energy and catalysis purposes [24,25], in addition to applications including biosensors and DDS [26]. More recently, Yang and Yang surveyed the current field of MOF-based biomedical materials, reporting advances in five areas including DDS, biosensing and biocatalysis [22].…”
