报告摘要:

Photochemical strategies have distinctive advantages in comparison to conventional methodologies in terms of mild reaction conditions, low energy requirements and temporal and dimensional control.^[1]After such benefits have been realized by the synthetic polymer community, photochemical reactions have been employed to a wide range of organic reactions, functionalization and polymerization processes. Specifically, photochemical radical generation is the most commonly applied strategy as the reactive nature of radicals make them useful not only for traditional polymerizations^[2]but also for controlled/living polymerizations.^[3-7]In addition, they can be utilized for the simultaneous generation of specific compounds, which can mediate various coupling reactions including click processes.^[8]This make them applicable to modification of polymers and syntheses of complex macromolecular structures such as telechelics, block and hyperbranched polymers.^[8-10]Below is the schematic representation of photoinduced radical generation and its applications to polymer chemistry.
