报告人简介：

Suzanne A. Blumgraduated from the University of California, Berkeley, working under the supervision ofBergman, R. G. After a postdoctoral stay at the National Institutes of Health in2004-2006, she returned to Department of chemistry at University of California, Irvine, where she was elected as a professor in 2017. She has published over 50 articles and filed two patents in the field of organic chemistry of metals. In 2013, she wasselected as Alexander von Humboldt Research Fellow. She has also been awarded lots of honors, including NSF (National Science Foundation) CAREER Award (2008), Thieme Synlett/Synthesis Journal Award (2009),Japan Society for Promotion of Science Fellowship (2013),Elected Fellow of the American Association for the Advancement of Science (2017).Her work focuses on the total synthesis of natural biologically-active products like anticancer agents, antibiotics,anti-inflammatoriesor products acting on the central nervous system. She has also conducted research on free-radical reactions andphotochemicalreactions. She pioneers new mechanisms for transition-metal reactivity with synthetic applications and aims to change the way people study chemical reactions by developing microscopy techniques to study mechanisms and catalysis.

为加强师生间的学术交流与合作，活跃学术氛围，增强科研实力，9月5日下午，高等研究院在当代楼五楼学术报告厅举办了长江学术论坛第85讲，邀请了Suzanne A.Blum教授作“单分子水平的有机化学”为题的学术报告。

Suzanne教授在报告中介绍了采用单分子荧光显微镜对过渡金属催化聚合成像的过程：采用一种高灵敏度、高分辨率的单粒子荧光显微技术，可通过对定位进行成像，在均相和非均相复分解聚合催化之间进行区分。通过对GrubsⅡ催化剂的单聚体和单晶的成像，发现聚合催化完全是均相的，而不是非均质的或两者兼而有之。此外，Suzanne教授的报告中解释了反应活性与结构之间的关系、不同的盐在微观尺度上的行为和动力学分布等问题。

报告结束后，参加报告的师生们与Suzanne教授就相关问题展开了深入的讨论。
