50th Anniversary Perspective: Polymer Functionalization

“…A few years later, Rowan and his team published a feature article reporting different examples of CuAAC to construct conjugated and/or functional heteroaromatic materials, such as tunable multichromophoric covalent ensembles or macrocyclic receptors . Hawker and co-workers have recently published a book chapter focusing on both CuAAC and thiol–ene coupling for the synthesis and functionalization of macromolecules . Importantly, Du Prez and Espeel have provided a perspective article covering recent progress in click-inspired chemistries in macromolecular science, providing insights into the state-of-the-art of different efficient conjugation methods, including CuAAC .…”

“…206 Hawker and co-workers have recently published a book chapter focusing on both CuAAC and thiol−ene coupling for the synthesis and functionalization of macromolecules. 207 Importantly, Du Prez and Espeel have provided a perspective article covering recent progress in click-inspired chemistries in macromolecular science, providing insights into the state-ofthe-art of different efficient conjugation methods, including CuAAC. 208 Finally, Gao and co-workers published a feature article highlighting the recent advances in the use of CuAAC reactions for the preparation of nanostructured polymers, especially branched polymers such as dendrimers, hyperbranched polymers, and star polymers.…”

Imidazolium-Based Polymers via the Poly-Radziszewski Reaction

“…Usually lengthy, multistep synthetic procedures are required to synthesize these IL monomers, which are not economically feasible due to low chemical yields and multiple purification steps. An alternative approach to PIL’s is the postfunctionalization of polymeric scaffolds, usually by means of “click reactions” such as copper-catalyzed azide–alkyne cycloadditions or thiol–ene additions. ,, Herein additional functional groups are necessary in either the polymer or the IL species, again resulting in a costly and time-consuming synthetic procedure.…”

Covalent Functionalizations of Poly(vinyl chloride) in Tune with Applications: An Update

“…Indeed, since its emergence in 2001 [9], click chemistry has opened new avenues not only in related chemistry synthesis [10,11], but also in several other research aspects [12,13]. Its application was even extended to polymer field for specific uses [14][15][16], and, more interesting, to biopolymers [17]. Like poly(vinyl alcohol) [18], poly(vinyl chloride) has undergone several covalent modifications using click chemistry.…”
