Chem. SOC. Rev: Professor Pan Xiangcheng's research group of Fudan University published a systematic review on externally regulated atom transfer radical polymerization

Atom transfer radical polymerization (ATRP) is based on simple organic halide as initiator and transition metal complex as catalyst Through atom transfer mechanism, a reversible dynamic balance is established between active species and dormant species, which is realized by too fast initiation, slow growth and reduction of free radical concentration It can control the free radical polymerization The concept was first proposed by Professor matyjaszewski in 1995 (J am Chem SOC 1995, 117, 5614 − 5615) In just over 20 years, atom transfer radical polymerization has become a research frontier in the field of polymer synthesis In recent years, the control of reaction by photochemistry, electrochemistry and other external control methods has been widely concerned Through external control, the time and location of the reaction can be precisely controlled, which is more important for polymerization In this review, the development history of atom transfer radical polymerization is reviewed firstly, and then several kinds of external control methods are systematically reviewed in chapters: electric control, optical control, mechanical control, chemical control and temperature control Finally, the author also puts forward the prospect of the current challenges and future development direction in this field Professor Pan Xiangcheng, Department of polymer science and State Key Laboratory of polymer molecular engineering, Fudan University, and Professor Krzysztof matyjaszewski, Carnegie Mellon University, USA were invited to publish relevant reviews on the topic of "externally controlled atom transfer radial polymerization" on chem SOC Rev Professor Pan Xiangcheng and Professor matyjaszewski are co authors.
