Direct Alkylation of Gold Surfaces with Solutions of Organometallics

12.08.2016 (Friday) , 10:00 - 11:30
Chemie-Neubau, CHE91 , Bergstraße 66 , 01069 Dresden

Upon treatment with dilute solutions of alkylstannanes and other main group organometallics under ambient conditions, alkyl groups longer than methyl are transferred to gold surface and form a disordered self-limiting monolayer. In most but not all cases, the metal is deposited as well, in elemental form or as an oxide. Spectral and other properties of the monolayer as well as the kinetics of its formation will be discussed and a possible mechanism for the surface alkylation proposed.

BIOGRAPHY:
Professor Josef Michl teaches in the Department of Chemistry and Biochemistry at the University of Colorado at Boulder. He is a native of Czechoslovakia, studied at the Charles University in Prague with V. Horák and P. Zuman, and the Czechoslovak Academy of Sciences with R. Zahradník, and obtained his Ph.D. in 1965. His post-doctoral experience was in chemistry with R.S. Becker at the University of Houston, M.J.S. Dewar at the University of Texas, A.C. Albrecht at Cornell University, and J. Linderberg at Aarhus University, and in physics with F.E. Harris at the University of Utah. He joined the faculty in the Chemistry Department at Utah in 1970 and was chairman of the department in 1979-84. He left Utah in 1986 and after a brief stint as Collie-Welch Regents Chair Professor at the University of Texas at Austin moved to his present position in Boulder. He has been a Sloan Fellow, a Guggenheim Fellow, and a Humboldt Senior U.S. Scientist awardee. He has held numerous visiting positions and named lectureships. He has received honorary degrees from Georgetown University in Washington, DC, and from University of Pardubice in the Czech Republic.
