“…The adsorption of bisphenols (BPA and BPAF) was influenced by various factors, including temperature, adsorbent dosage, pH, and salt concentration. [79] As mentioned in reference, the adsorbent demonstrated outstanding adsorption performance for BPA and BPAF, with maximum adsorption capacities of 140 mg/g and 290.4 mg/g, respectively. [75] A new Lewis acid-catalysed procedure which directly produced boronate esters from aryl boronic acids and protected catechol was published in 2010 by Eric L. Spitler et al [80] In addition, crystalline boronate ester-linked COFs have been produced by this reaction from bis-protected polyfunctional catechol's.…”

Covalent organic frameworks (COFs) distinguish themselves from conventional materials by their exceptional combination of characteristics, including a well‐defined crystalline structure, inherent porosity, substantial surface area, remarkable design flexibility, capacity for functionalization, and chemical tunability. These attributes collectively contribute to the distinctiveness and versatility of COFs compared to traditional materials. This opens up exciting possibilities for multiple applications including energy storage, sensing, gas extraction and catalysis. The extraordinary stability of COFs in aqueous solutions and under harsh climatic conditions opens up new applications for them, including water treatment. COFs are attractive materials for tackling water pollution concerns and expanding their applications in related fields as a result of their distinctive attributes, like remarkable adsorption ability and adjustable architectures. The use of COF membranes in effluent management can improve the elimination of harmful dyes, resulting in better water quality and environmental protection. The creation of COF‐based membranes is a significant step forward in the field of water filtration and shows great potential for solving the issues faced by industrial wastewater contamination. Many published techniques provide continuous COF‐based membranes that fully utilize COFs for separations. Performance and characterization of COF‐membranes can be arbitrated with the help of various analytical and spectroscopic methods. The present study marks the most important structural characteristics and functional design methodologies of COFs in the form of thin membranes for dye separation. A discussion on the characteristics of COFs responsible for membrane separation with their synthesis and characterizations has also been done. Various reported fabrication methods of COF based membranes for dye removal are discussed concisely.

“…The analytes are desorbed from the magnetic nanoparticles via a solvent or mixture of solvents, which will be recovered and further processed [62,63]. There are several magnetic materials implemented in this technique, such as polymers, carbon nanotubes, graphene composites, ionic liquids, deep eutectic solvents with hydrogen bond interactions, MOFs, boronate affinity materials, host-guest molecular recognition by supramolecules, aptamers, polydopamine (PDA), MIPs and MIP-carbon compounds and covalent organic structures (COFs), which present hydrogen bonds, the effect of pore size and hydrophobic and π-π interactions as the main adsorption mechanisms [64][65][66][67][68][69]. The non-covalent methods such as π-π stacking interactions are frequently used to prepare graphene-based composites [70], and ionic liquids provide hydrogen bonding, dipole-dipole and ionic interactions with the analytes [13].…”

Solid Phase-Based Microextraction Techniques in Therapeutic Drug Monitoring

et al. 2023

Therapeutic drug monitoring is an established practice for a small group of drugs, particularly those presenting narrow therapeutic windows, for which there is a direct relationship between concentration and pharmacological effects at the site of action. Drug concentrations in biological fluids are used, in addition to other clinical observation measures, to assess the patient’s status, since they are the support for therapy individualization and allow assessing adherence to therapy. Monitoring these drug classes is of great importance, as it minimizes the risk of medical interactions, as well as toxic effects. In addition, the quantification of these drugs through routine toxicological tests and the development of new monitoring methodologies are extremely relevant for public health and for the well-being of the patient, and it has implications in clinical and forensic situations. In this sense, the use of new extraction procedures that employ smaller volumes of sample and organic solvents, therefore considered miniaturized and green techniques, is of great interest in this field. From these, the use of fabric-phase extractions seems appealing. Noteworthy is the fact that SPME, which was the first of these miniaturized approaches to be used in the early ‘90s, is still the most used solventless procedure, providing solid and sound results. The main goal of this paper is to perform a critical review of sample preparation techniques based on solid-phase microextraction for drug detection in therapeutic monitoring situations.

“…COFs are organic porous polymers connected by covalent bonds, resulting in permanent porosity, periodic arrangement, and thermal/chemical stability. [26][27][28][29] Therefore, COFs are widely used in sensing, [30] gas absorption/storage, [31] and catalysis [32] due to the convenience for characterization. Although COFs materials have long-range ordered structures and large specific surface areas, their synthesis conditions are more stringent and the mechanism has not been well revealed.…”

The establishment of green and environmental friendly sunlight‐driven organic reactions has received increasing attention since the 21st century. By virtue of their functional designability, micromesoporous structure, and thermal/chemical stability, porous organic polymers (POPs) have exhibited enormous promise in photocatalytic organic reactions as ideal potential alternatives to conventional small molecule and inorganic semiconductor catalysts. In particular, amorphous POPs are simplified in terms of preparation conditions and process flow. Herein, various amorphous POP materials based on polymers of intrinsic microporosity, hypercrosslinked polymers, conjugated microporous polymers, and porous aromatic frameworks are reviewed, while typical synthetic strategies are briefly introduced. It also highlights an overview of the research progress in photocatalytic oxidation, coupling, reduction, cycloaddition, and polymerization reactions at home and abroad in recent years. Finally, the challenges and prospects for future research on amorphous POPs are presented.
