Chemistry Seminar Program
Inorganic Chemistry Seminar Monday, January 22nd Professor Moris S. Eisen "Designing Octahedral Complexes for the Polymerization of a-Olefins. From Atactic and Isotactic to Elastomers "  4:15pm - 5:15pm Braun Lecture Hall S.G.Mudd Chemistry Building Stanford University This seminar is free and open to the public. All Stanford University Chemistry students are encouraged to attend this special event. About the seminar Group IV metallocenes are used as homogeneous precatalysts for a wide variety of processes. The study of ligand effects on the polymerization of a-olefins, using soluble group IV metallocenes/co-catalyst systems has shed a great deal of light on the mechanism of this important process, focusing mainly on cyclopentadiene ligand based complexes as well as their derivatives. This presentation will report the synthesis and activity of a number of octahedral catalysts for the polymerization of a-olefins. We will show how the tacticities of the polymers can be modulated by simple external pressure. In addition we will present labeling experiments to get mechanistic insights for the formation of elastomeric polypropylene, predicting a new epimerization mechanism. About Eisen: Professor Moris Eisen, originally from Bogota, Colombia South America received his BS from Hebrew University of Jerusalem, Israel. In 1990 his graduated with his PhD. from Hebrew University of Jerusalem, Israel with Prof. Jochanan Blum. Eisen did his Postdoc work at the Northwestern University and then in 1993 took a senior lecturer at Technion Haifa University. In 1999 he was named an Associate Professor at the Faculty of Chemistry at the same university. The same year Eisen won the Mitchel-Soref Research Award, Alexander Goldberg Excellence in Research Award, and the Herschl Rich Technion Innovation Award. He is currently a full professor and in 2006 he was name the Incumbent of the Samuel O. Friedlander Academic Chair in Chemistry at Technion Haifa 32000, Israel. Eisen has won various awards and honors for his work in inorganic chemistry including the Germany Humboldt Foundation) (2000-2001), the Mitchel Soref Research Award (2001-2002) and the Henry Taub Research Prize Award (2002-2003).
