报告摘要
Molecular translational or rotational motors are architecture for which movements between a fixed and a mobile portion may be induced by external stimuli.1 As a first step towards molecular motors, a series of molecular turnstiles have been designed and synthesized. The first category is based on Sn(IV)porphyrins as stators bearing at the meso positions interactions sites and equipped with different handles as rotors. The connection between stators and rotors is achieved through Sn-O (Fig. 1).2-7 The second design principle is based on the covalent attachment of the rotor to the stator using two opposite meso positions on the porphyrin backbone (strapped porphyrins) (Fig. 2).8,9 Finally, the tired approach is based on organometallic Pt complexes as rotors and coordinating handles as stators (Fig. 3).10-14
The design, synthesis and structural characterizations, both in solution by multidimensional 1H-NMR techniques and in the solid state by X-ray diffraction on single crystals, of a series of molecular gates and turnstiles will be presented and discussed.

 


报告人简介:
Mir Wais Hosseini, exceptional class Professor at the University of Strasbourg, was born in Kabul, Afghanistan. He was educated at the higher level at the University Louis Pasteur. He started his research career under the supervision of Jean-Marie Lehn and worked with him during 10 years. At the age of 26, he was offered a permanent position by the French National Research Centre and at the age of 35, became full professor. He was triply elected to the Institut Universitaire de France (IUF, Chair of Molecular Tectonics). In 2006, he was elected as a member of Academia Europaea. In 2010, he was the winner of the binational (Italy-France) award by the Italian and French Chemical Society, in 2011, he was awarded with the Silver Medal of the CNRS and in 2012 he was the winner of the binational (German-France) Grignard-Wittig award by the German Chemical Society (GDCH). In 2013 he received the prestigious Alexander von Humboldt Research Award and in 2014, he was awarded with the Izatt Christensen Award in Macrocyclic Chemistry. In 2014, he became "Chevalier de la Légion d'Honneur". He has supervised 41 PhD students, 5 "Habilitations" and > 100 graduate and undergraduate students and postdoctoral fellows. He has published > 300 manuscripts and delivered some 430 invited lectures. He was invited Professor at University of Geneva, University of Western Australia, Tsukuba Research Centre, University of Tokyo, Academia Sinica, University of Kyoto, University of Hokkaido and Politecnico di Milano.
