Synthetic Methodologies for Chelating Polymer Ligands: Recent Advances and Future Development

Abstract

This review summarizes recent progress in synthetic methodologies of chelating polymer ligands such as linear, branched, cross‐linked, grafted polymers, polymer films, liquid crystal polymers, dendrimers, star‐shaped and hyperbranched polymers. The features of methods for producing chelating polymer ligands are considered in detail: free‐radical (co)polymerization, living/controlled radical, metathesis, grafted, chemical oxidized, microwave‐assisted and asymmetric polymerization, electropolymerization, cyclopolymerization, polycondensation, post‐polymerization modification, click chemistry methods and “green” synthesis. The main directions of the development of synthetic chemistry of chelating polymeric ligands are analyzed. The bibliography includes works published in the last five years.

Facile Construction of Microgel based Biomimetic Glutathione Peroxidase with Temperature Responsive Catalytic Activity

“…ATRP is a controllable polymerization technology, which can be used to prepare novel polymer materials with controllable structures . One‐pot synthesis method is a simple and efficient method to prepare various functional materials . Integrating ATRP technology with the one‐pot synthesis, a simple and efficient strategy for preparing temperature responsive PAMTegel is presented in Scheme .…”

“…When the temperature was elevated to the neighborhood of LCST of PNIPAM (between 33 and 37°C), the PNIPAM molecular chains changed from the hydrophilic unit to hydrophobic unit, which led to a phase transition of PNIPAM and a shrinkage of the PNIPAM layer. [52] Consequently, the PAMTegel solution became turbid and the the hydrodynamic diameter of PAMTegel was decreased. For instance, the hydrodynamic diameters for PAMTegel at 35°C (Figure 4c) and 37°C (Figure 4b) were about 490 nm and 360 nm, respectively, which are smaller than that of PAMTegel at 25°C.…”

“…One‐pot method is a simple and efficient method to prepare various functional materials, and ATRP is a favorable approach to prepare structurally controllable polymers . Combining the advantages of one‐pot synthesis and ATRP, we successfully developed a new strategy to prepare biomimetic GPx ( PAMTegel ) with temperature responsive catalytic activity in this work.…”

“…One-pot method is a simple and efficient method to prepare various functional materials, [50] and ATRP is a favorable approach to prepare structurally controllable polymers. [51,52] Combining the advantages of one-pot synthesis and ATRP, we successfully developed a new strategy to prepare biomimetic GPx (PAMTegel) with temperature responsive catalytic activity in this work. For preparing PAMTegel, acrylamide, crosslinker, and the tellurium-containing polymerizable monomer were firstly co-polymerized and acted as the core of PAMTegel that offered the biomimetic GPx with catalytic center.…”

The Effect of Cellulose Acetate in the Inhibition of Bacteria: an Alternative for Antimicrobial Resistance

“…That is why, investigations into this problem and a search for solutions have been presented in many scientific articles [3][4][5]. It should be noted that, the researchers' attention in recent years [6][7][8] has been focused on finding chemically modified polymeric supports with biologically active groups which have antimicrobial properties. Polymeric biocides obtained by the chemical bonding of antimicrobial active groups on insoluble polymers have attracted a lot of interest due to the fact that they can be recovered and used for a longer period of time.…”
