“…However, changes in monomer structure can also be expected to impact other polymerization conditions such as In addition to these alkane-functionalized methacrylates, a number of methacrylates with heteroatom-containing aliphatic groups have been polymerized successfully. These monomers include methacrylic acid, 170 2-hydroxyethyl methacrylate, 87 diethylene glycol methyl ether methacrylate, 155 poly(ethylene glycol) methacrylate, 97,122 glycidyl methacrylate, 171 and diethylamino ethyl methacrylate. 171 A number of aromatic monomers have also been polymerized, including benzyl methacrylate 33,35 and furfuryl methacrylate, 66,172 although not as extensively as aliphatic methacrylates.…”

“…173 In other work, researchers disclosed the polymerization of 2-([4,6-dichloro-triazin-2-yl]oxy)ethyl methacrylate, 94 pyrenyl methacrylate, 94 and even fluorescein-o-methacrylate. 174 In addition, several bifunctional monomers have been reported in O-ATRP, such as allyl methacrylate, 171 methacrylate-based inimers (monomers that can also serve as initiators), 175 and dimethacrylate monomers to achieve polymer cross-linking. 176 Because of the complex polymer architectures achieved using such monomers, in particular inimers and dimethacrylates, polymerization control in these systems often cannot be evaluated.…”

The development of photoinduced organocatalyzed atom transfer radical polymerization (O-ATRP) has received considerable attention since its introduction in 2014. Expanding on many of the advantages of traditional ATRP, O-ATRP allows well-defined polymers to be produced under mild reaction conditions using organic photoredox catalysts. As a result, O-ATRP has opened access to a range of sensitive applications where the use of a metal catalyst could be of concern, such as electronics, certain biological applications, and the polymerization of coordinating monomers. However, key limitations of this method remain and necessitate further investigation to continue the development of this field. As such, this review details the achievements made to-date as well as future research directions that will continue to expand the capabilities and application landscape of O-ATRP. CONTENTS 4.5.

“…The synthesis of homopolymers and block copolymers by O‐ATRP is well‐known and has been explored by several authors. [ 112–114 ] Therefore, scientists often synthesize these types of polymers as part of more complex structures. The efforts to simplify the synthesis of block copolymers are notable.…”

Reversible deactivation radical polymerization (RDRP) is a class of powerful techniques capable of synthesizing polymers with a well‐defined structure, properties, and functionalities. Among the available RDRPs, ATRP is the most investigated. However, the necessity of a metal catalyst represents a drawback and limits its use for some applications. O‐ATRP emerged as an alternative to traditional ATRP that uses organic compounds that catalyze polymerization under light irradiation instead of metal. The friendly nature and the robustness of O‐ATRP allow its use in the synthesis of tailorable advanced materials with unique properties. In this review, the fundamental aspects of the reductive and oxidative quenching mechanism of O‐ATRP are provided, as well as insights into each component and its role in the reaction. Besides, the breakthrough recent studies that applied O‐ATRP for the synthesis of functional materials are presented, which illustrate the significant potential and impact of this technique across diverse fields.

“…Amphiphilic block copolymer attracts considerable attention due to its self-assemble ability, and has been widely used in drug and gene delivery areas [ 162 , 163 , 164 , 165 ]. Son et al reported that an amphiphilic diblock copolymer could be prepared through metal-free ATRP by using Ph-PTZ as organic photocatalyst under the irradiation of LED light (380 nm) [ 166 ]. This method was also successfully applied to the polymerization of MMA, GMA, BA, 2-diethylaminoethyl methacrylate (DEAEMA), and allyl methacrylate (AMA).…”

Atom transfer radical polymerization (ATRP) is one of the most successful techniques for the preparation of well-defined polymers with controllable molecular weights, narrow molecular weight distributions, specific macromolecular architectures, and precisely designed functionalities. ATRP usually involves transition-metal complex as catalyst. As the most commonly used copper complex catalyst is usually biologically toxic and environmentally unsafe, considerable interest has been focused on iron complex, enzyme, and metal-free catalysts owing to their low toxicity, inexpensive cost, commercial availability and environmental friendliness. This review aims to provide a comprehensive understanding of iron catalyst used in normal, reverse, AGET, ICAR, GAMA, and SARA ATRP, enzyme as well as metal-free catalyst mediated ATRP in the point of view of catalytic activity, initiation efficiency, and polymerization controllability. The principle of ATRP and the development of iron ligand are briefly discussed. The recent development of enzyme-mediated ATRP, the latest research progress on metal-free ATRP, and the application of metal-free ATRP in interdisciplinary areas are highlighted in sections. The prospects and challenges of these three ATRP techniques are also described in the review.
