Flexible to rigid: IR spectroscopic investigation of a rhenium-tricarbonyl-complex at a buried interface


Oppelt, Kerstin T; Sevéry, Laurent; Utters, Mirjam; Tilley, S David; Hamm, Peter (2021). Flexible to rigid: IR spectroscopic investigation of a rhenium-tricarbonyl-complex at a buried interface. Physical Chemistry Chemical Physics (PCCP), 23(7):4311-4316.

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.
