“…This CTF was found to be fluorescent both in suspension and in solid state, and thanks to its electron-rich structure, it was successfully applied to the detection of nitroaromatic compounds, both in solution and in vapor phase. [118] If SNW-1 was synthetized in presence of a NH 2 -functionalized magnetite (Fe 3 O 4 ), a layer of CTF with a thickness slightly lower than 40 nm was homogenously formed on the magnetite surface [SNW-1 (Fe 3 O 4 )] after a reaction time of 4 h. [119] The produced composite showed high selectivity for the coordination of Hg II over many others metal ions and a high adsorption capacity of almost 100 mg Hg g À 1 . Apart from magnetite, SNW-1 can be synthesized separately under microwave irradiation following a complex process at different temperatures, and then deposited over a SiÀ OHactivated silica forming a variable thickness layer.…”

“…In addition to the main advantage, related to the reduction in time, microwaves are particularly interesting for the preparation of some materials such as nanomagnetite containing COFs, [110,119] COFs loaded with metallic nanoparticles, [112] or carbonaceous materials that maintain partially the COF structure. [121] Also, some materials can be obtained under MAS (Microwave Assisted Synthesis) conditions only.…”

Covalent organic frameworks (COFs) are relatively recent materials. They have received great attention due to their interesting properties. However, the application of microwaves in their synthesis, despite its advantages such as faster and more reproducible processes, is a minority. Herein, a comprehensive compilation of the research results published in the microwave‐assisted synthesis (MAS) of COFs is presented. This review includes articles of 2D and 3D COFs prepared using microwaves as source of energy. The articles have been classified depending on the functional groups including boronate ester, imines, enamines, azines, and triazines, among others. It compiles the main parameters of synthesis and characteristics of the materials together with some general issues related with COFs and microwaves. Additionally, current and future perspectives of the topic have been discussed.

“…These frameworks possessed remarkable thermal stability (400 °C) and were stable in water and common organic solvents. However, their PXRD signals were not satisfactory [ 134 ]. Recently, Yang and co-workers synthesized another melamine-based COFs based on the condensation of melamine and chlorinated triazine [ 135 ].…”

“…Moreover, this method was also suitable for unsealed system and could be used for both 2D and 3D COFs (COF-102) [ 144 ]. In addition of boron-based COFs [ 157 , 158 ], microwave synthesis has been explored to form β-ketoenamine [ 159 , 160 ], triazine [ 128 ] and melamine [ 106 , 134 ] based COFs.…”

Covalent organic frameworks (COFs) are newly emerged crystalline porous polymers with well-defined skeletons and nanopores mainly consisted of light-weight elements (H, B, C, N and O) linked by dynamic covalent bonds. Compared with conventional materials, COFs possess some unique and attractive features, such as large surface area, pre-designable pore geometry, excellent crystallinity, inherent adaptability and high flexibility in structural and functional design, thus exhibiting great potential for various applications. Especially, their large surface area and tunable porosity and π conjugation with unique photoelectric properties will enable COFs to serve as a promising platform for drug delivery, bioimaging, biosensing and theranostic applications. In this review, we trace the evolution of COFs in terms of linkages and highlight the important issues on synthetic method, structural design, morphological control and functionalization. And then we summarize the recent advances of COFs in the biomedical and pharmaceutical sectors and conclude with a discussion of the challenges and opportunities of COFs for biomedical purposes. Although currently still at its infancy stage, COFs as an innovative source have paved a new way to meet future challenges in human healthcare and disease theranostic.

Summary Covalent organic frameworks (COFs) are a new type of crystalline porous polymers known for chemical stability, excellent structural regularity, robust framework, and inherent porosity, making them promising materials for capturing various types of pollutants from aqueous solutions. This review thoroughly presents the recent progress and advances of COFs and COF-based materials as superior adsorbents for the efficient removal of toxic heavy metal ions, radionuclides, and organic pollutants. Information about the interaction mechanisms between various pollutants and COF-based materials are summarized from the macroscopic and microscopic standpoints, including batch experiments, theoretical calculations, and advanced spectroscopy analysis. The adsorption properties of various COF-based materials are assessed and compared with other widely used adsorbents. Several commonly used strategies to enhance COF-based materials’ adsorption performance and the relationship between structural property and sorption ability are also discussed. Finally, a summary and perspective on the opportunities and challenges of COFs and COF-based materials are proposed to provide some inspiring information on designing and fabricating COFs and COF-based materials for environmental pollution management.
