报告题目Chiral Br?nsted acids: What can be gained from multifunctional systems for chemosensing and organocatalysis?

人:Prof. Jochen Niemeyer

报告时间:2019521日(周二)上午9:00

报告地点:化学楼一号会议室

人:蒋皓 副研究员

报告人简介:

Jochen Niemeyer,博士,德国杜伊斯堡-埃森大学青年团队负责人。2009年于德国明斯特大学获得化学博士学位,然后分别在明斯特大学和英国剑桥大学从事博士后研究工作,之后于2011年加入德国赢创公司任实验室研发主管。2014年加入杜伊斯堡-埃森大学Prof. Carsten Schmuck团队任青年团队负责人。Jochen Niemeyer博士目前的研究兴趣主要包含有机化学合成和功能性超分子体系的构建,以及基于DNA体系在催化和传感中的应用。在Angew. Chem. Int. Ed., J. Am. Chem. Soc., Chem. Eur. J., Org. Lett.等期刊发表了20多篇论文。

报告简介:

Our research focuses on the development of bi- and polyfunctional covalent and mechanically interlocked frameworks. In this context, we are currently pursuing the synthesis of bis- and tris-1,1&acute;-binaphthyl-phosphoric acids using different strategies. On one hand, we perform a covalent coupling of 1,1&acute;-binaphthyls via the 3,3&acute;- or 4,4&acute;-positions to give bis- and trisphosphates of different geometry. On the other hand, we are investigating the incorporation of 1,1&acute;-binaphthyl-phosphoric acids in interlocked catenane- or rotaxanestructures, thus resulting in bifunctional interlocked molecules.

 The resulting bisphosphates are investigated with regard their application as ditopic artificial receptors and as bifunctional organocatalysts. This will allow a comparison of the effects of the different linking strategies, evaluating whether a rigid predefined geometry or a more flexible interlocked arrangement is of advantage for the different applications of these bifunctional molecules.
