Abstract

A study that illustrates the straightforward chemical modulation of the optical absorbance of a thermally monolayer in air by exploitation of redox properties of metal complex, is presented. The monolayers have been demonstrated as thermally robust, and 25 Os²⁺/Os³⁺ redox cycles. the solution-surface electron transfer process induced changes in the molecular properties of the monolayer have been monitored by UV/vis transmission spectroscopy. This siloxane-basaed monolayers and surface chemistry could open up new opportunities in interfacial engineering and the formation of monolayer-based memory devices.
