Attachment of Molecules at a Molecular Printboard by Multiple Host–Guest Interactions

Abstract

Monolayers of cyclodextrin host molecules on gold substrates are used as “molecular printboards” for the stable attachment of functionalized molecules through multiple supramolecular interactions. Adsorption is achieved through delivery as a supramolecular complex (see picture), whereas the desorption kinetics can be tuned by varying the cyclodextrin concentration in solution.
