报告摘要：
具有精确定序结构的聚合物在多个应用领域中展现出巨大的潜力。在自然界中，核酸和蛋白质等具有特定序列与复杂结构功能的生物聚合物，能够通过复杂的生物途径由单体混合物自发生成。然而，在高分子化学的人工合成中，实现与生物体系相当程度的单体序列控制仍是一项重大挑战。本报告将介绍在阴离子开环共聚反应中实现单体序列可控聚合的方法。通过根据单体的反应特性合理选择单体组合，实现嵌段共聚物的精确合成。以及，利用双组分有机催化体系调控共聚过程中单体的相对反应活性，从而实现聚合物单体序列的控制。

报告人简介：
Feng Li is an Assistant Professor at the Faculty of Engineering at Hokkaido University in Japan. He earned his Bachelor's degree from Peking University, China, in 2011 and Ph.D. degree in organic chemistry from Tohoku University, Japan, in 2016. After completing his Ph.D., he conducted postdoctoral research in polymer chemistry field at Yale University, USA, and at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, from 2017 to 2020. At the end of 2020, he moved to Kanazawa University, Japan, as a Specially Appointed Assistant Professor. In May 2022, he joined his current position at Hokkaido University. His expertise is in polymer chemistry and organic chemistry. His current research interests are centered on sustainable polymer synthesis, which includes utilizing renewable biomass materials, chemically recyclable polymer materials, and developing environmentally friendly catalysts. He has received the Polymer Research Encouraging Award from the Society of Polymer Science, Japan in 2024.
报告摘要：
Using biomass for sustainable polymer production is a key strategy in addressing global challenges such as plastic waste and fossil fuel depletion. Cellulose, the most abundant non-edible biopolymer on Earth, holds significant promise. Levoglucosenone (LGO) and dihydrolevoglucosenone (CyreneTM), two cellulose-derived compounds conventionally used in organic synthesis, started to be utilized in polymer synthesis in recent years. Here, new strategies and recent results on developing novel polymer materials, including unnatural polysaccharides, acetal copolymers, polyesters, and polyethers, from these two cellulose-derived compounds will be reported.
