报告人简介：

Robert B. Grubbs，康奈尔大学博士、宁波大学包玉刚讲座教授、纽约州立大学教授。1993年荣获美国国家自然科学基金会CAREER Award，其前身为美国总统青年科学家奖（Presidential Young Investigator's Award)。

Robert B. Grubbs教授的专长在于利用高分子化学、有机化学、材料化学之间的共通点参与设计、合成和表征聚合物基有机材料。通过向自然界生物的学习，以形似、神似、超越三类模仿方法进行多尺度分子的仿生设计、化学合成和成型加工，把新颖的聚合物和嵌段共聚物应用于各种领域。

现研究方向为：聚合物分子设计与可控聚合、自组装、功能高分子。

报告摘要：

Controlled and living polymerization techniques have proven indispensable for the synthesis of new block copolymers and copolymer-based materials. We have used nitroxide-mediated radical polymerization (NMP), atom transfer radical polymerization (ATRP), reversible addition-fragmentation-chain transfer (RAFT) polymerization, and ring-opening polymerization (ROP) for the preparation of a range of copolymer architectures, including block copolymer/metal nanoparticle composites and aqueous stimulus-responsive block copolymer assemblies.  Block copolymers with alkyne-functional blocks for the ultimate preparation of cobalt nanoparticles have been prepared with some success by direct NMP of alkyne-functional monomers.  Amphiphilic block copolymers designed to assemble into stimulus-responsive micelles in water have been prepared by NMP, ATRP, RAFT, and ROP from poly(ethylene oxide) macroinitiators. We have also synthesized amphiphilic star-block copolymers through a combination of synthetic methods. The synthesis and characterization of these and other copolymer-based materials will be discussed.
