Angel E. Kaifer博士学术报告会

受浙江大学理学院化学系黄飞鹤超分子化学课题组的邀请，美国迈阿密大学教授Angel E. Kaifer博士将于5月22日访问我校。Angel E. Kaifer博士学术报告将于5月22日下午三点举行，欢迎各位老师和同学积极参加！Kaifer教授的研究领域包括：Electrochemistry of supramolecular systems， host-guest complexation and molecular recognition， functionalized dendrimers and metal nanoparticles。Kaifer教授获得超过$4,000,000的研究经费，发表了超过170篇论文，著有一本书和十五本书中的某些章节。担任过Langmuir (1995-1997), Supramolecular Chemistry (1992至今) and Journal of Supramolecular Chemistry (1997-2003)的编委。是NSF和NIF的评审专家，并且现在是NIH Study Section on Nanotechnology in Medicine的常委。学术报告题目：Cucurbit[n]urils: A New Class of Molecular Receptors with Unusual Binding PropertiesThe cucurbit[n]urils are readily prepared by condensation of glycoluril with formaldehyde in acidic medium. This reaction yields a complex mixture of products from which it is possible to isolate the hexameric (CB6), heptameric (CB7) and octameric (CB8) cucurbiturils, among many other compounds. The cucurbit[n]urils are macrocyclic structures in which n glycoluril units, linked by methylenes, form container-shaped molecules with a rigid and well-defined cavity. The two identical cavity portals are lined by the carbonyl groups of the glycoluril units. The cucurbituril hosts from highly stable inclusion complexes in which the included guest (ideally a hydrophobic cation) develops hydrophobic contacts with the inner surface of the cavity and ion-dipole interactions with the carbonyl oxygens on the portals. In this lecture, I will focus on the properties of the inclusion complexes formed between the hosts CB7 and CB8 and two classes of redox active guests, viologen and ferrocene derivatives, highlighting the outstanding levels of binding affinity and selectivity that can be reached, particularly in the case of the ferrocene derivatives.地点：玉泉校区教八 (化学楼) 218室 时间：2009年5月22日(星期五)下午15:0017:00联系人：黄飞鹤教授， 87953189
