    • was born in Haifa, Israel in 1946. He studied chemistry at the Bar-Ilan University in Romat-Gan, Israel, and received his B.Sc. in 1969. He received his M.Sc. in phosphorus chemistry from Bar-Ilan University in 1971. After a brief period in industry, he moved to the Weizmann Institute in Rehovot, Israel, and received his Pd.D. in 1978 for work on heterosubstituted porphyrins. He then spent two years at Northwestern Univesity in Evanston, Illinois, where his main interest was one-dimensional organic conductors. Since 1985 he has been with the Corporate Research Laboratories, of Eastman Kodak Company, in Rochester, New York, where he is currently a research associate. His research interests encompass nonlinear optics, self-assembled monolayers, and surface engineering.


Optoelectronics and molecular electronics are two areas of potential application for monolayers of ordered organic materials. These layers from spontaneously on the immersion of an appropriate substrate into a solution of an active surfactant in an organic solvent. Very strong molecule–substrate interactions result, for example between the organo-siloxane trimer and a hydroxylated surface (see figure). The build up of mono and multilayers, the nature of the interface interactions and the applications of these organized structures are discussed.
