聚合物分子量分布是决定聚合物材料性能的重要参数。然而，以往的工作主要注重于合成分子量可控且分子量分布较窄的聚合物。近年来，发展调节分子量分布宽度与形状的新方法引起了人们的广泛重视，已成为高分子合成领域新的挑战。本项目拟为调节聚合物分子量分布的宽度及形状提供新方法，即潜在引发剂/调控试剂策略。该方法通过引入高效的光反应，在聚合过程中利用外部光源的开关来控制体系中引发剂或调控试剂的生成时间和生成量，利用光控反应便利的时空控制能力，达到不同分子量聚合物链的生成时间和生成量的调控，实现调节分子量分布的目的。利用这种潜在引发剂/调控试剂策略，将聚合物分子量分布调节转变为外部光源开关及光照时长的控制，简化操作，为聚合物的精密合成提供新的思路。进一步将外部光源参数的设定转变为计算机语言，构建出程序控制聚合物分子量分布的方法，推动人工智能技术在高分子合成领域的应用。

Polymer molecular weight distribution (MWD) is one of the key parameters that determines the properties of polymeric materials. However, previous work mainly focused on synthesizing polymers with controlled molecular weight and narrow MWD. The breadth and shape of MWD is far from fully understood. Such key point only has been paid attention to until recent years. Controlling the shape of MWD has become one of the challenges in the field of polymer synthesis. On this basis, the current project proposed photo-controlled latent initiator/mediator strategies to tailor both the breadth and shape of MWD. The key to build this strategy is to control the generation of initiator/mediator at different time utilizing the brilliant temporal and spatial control of photo-induced reactions, which will finally form polymers with different molecular weights by adjusting the external stimulate during the polymerization procedure. Benefiting from this strategy, the operation for tailoring MWD is simplified and a novelty avenue is provided. In addition, the parameters for adjusting the light can be transferred to computer language to construct programming-controlled system for the tuning of breadth and shape of MWD, which will promotes the application of artificial intelligence technology in the field of polymer synthesis.
