時(shí)間：2019年9月23日（周一）上午10：00 
地點(diǎn)：化學(xué)A樓518會(huì)議室

邀請(qǐng)人：顏徐州 研究員


報(bào)告人介紹：

Sander studied chemistry at the University of Nijmegen where he carried out his Master\'s research in the group of Prof. Roeland Nolte. He then moved to Tarragona for his PhD studies in the field of supramolecular chemistry with Prof. Arjan Kleij at the Institute of Chemical Research of Catalonia (ICIQ). During this period he spent three months as a visiting researcher in the group of Prof. Joseph Hupp at Northwestern University. After receiving his PhD in 2011, he joined the group of Prof. Fran?ois Diederich at ETH Zurich as a postdoctoral fellow. He came to the University of Groningen in 2013 to work with Prof. Ben Feringa and was later appointed Assistant Professor. In 2019, He moved to Leiden University to establish his independent research group. His main research interests are in the areas of anion binding, molecular switches, and self-assembled materials.


報(bào)告內(nèi)容介紹：

Stimuli-responsive molecular systems that mimic the highly complex and dynamic functions found in nature (e.g. allostericity, signalling, motion and transport) are receiving major interest and will form the basis of future nanomachines. In this context, molecular switches and motors that are activated by light are emerging as powerful tools to control the properties of materials as well as biological functions.[1]
In this presentation, synthetic systems in which control of motion at the molecular level is coupled to specific functions will be discussed. Particular focus is on the use of light-driven molecular switches and motors for the modulation of receptor-ligand interactions and self-assembly processes.[2] Finally, strategies to regulate the speed of rotation and to red-shift the excitation wavelength of these molecular motors are illustrated.[3]
