Abstract

Abstract : Immobilized rhenium tricarbonyl complexes were embedded in ALD deposited ZrO2, and investigated by (time resolved) infrared spectroscopy. The initially solvent exposed molecules react on the change of their environment. Abstract : This work explores the solid–liquid interface of a rhenium-tricarbonyl complex embedded in a layer of zirconium oxide deposited by atomic layer deposition (ALD). Time-resolved and steady state infrared spectroscopy were applied to reveal the correlations between the thickness of the ALD layer and the spectroscopic response of the system. We observed a transition of the molecular environment from flexible to rigid, as well as limitations to ligand exchange and excited state quenching on the embedded complexes, when the ALD layer is roughly of the same height as the molecules.
