Abstract
Gold clusters protected by 3-mercaptophenylboronic acid (3-MPB) with a mean core diameter of 1.1 nm are successfully isolated, and their absorption, magnetic circular dichroism (MCD), and chiroptical responses in metal-based electronic transition regions, which can be induced by surface D-/L-fructose complexation, are examined. It is well-known that MCD basically corresponds to electronic transitions in the absorption spectrum, so simultaneous deconvolution analysis of electronic absorption and MCD spectra of the gold cluster compound is conducted under the constrained requirement that a single set of Gaussian components be used for their fitting. We then find that fructose-induced chiroptical response is explained in terms of the deconvoluted spectra experimentally obtained. We believe this spectral analysis is expected to benefit better understanding of the electronic states and the origin of the optical activity in chiral metal clusters.
