Site affinity effects upon charge injection into siloxane-based monolayers

J Phys Chem B. 2006 Feb 2;110(4):1506-8. doi: 10.1021/jp0567164.

Abstract

Submolecular electrical information is successfully derived by applying element-specific, chemically resolved electrical measurements to a covalently bound stilbazole-based monolayer on a silicon substrate. Pronounced affinity effects are found in the response of adjacent atomic sites to external charge injection, accompanied by intramolecular polarization variations. These noncontact electrical read-out capabilities may provide a first entry toward the realization of organic devices based on submolecular electrical units.
