Induced circular dichroism (CD) band on plasmon region of metal nanoclusters by chiral metal complexes is described. The CD by chiral substances is also known to occur for metal nanoclusters, along with resonance plasmon absorption that shifts depending on the particle size. Some of the mechanisms of interactions between nanoparticles and plasmon have been clarified theoretically. Furthermore, applications such as the detection of biomolecules are expected for not only spectroscopic methods but also imaging methods. In addition to metal nanoclusters, chiral Schiff base metal complexes, such as azo-dyes, achiral metal complexes, metal dendrimers, metal oxide semiconductors, and proteins, exhibit unique optical absorption bands. It has been reported that an induced CD band is observed due to molecular alignment, e.g., in aggregates or dyes in crystal. This short review introduces the possibility of supramolecularly imparting chirality effects and functions to various materials such as colloidal gold by enumerating CDs induced by (azobenzene-containing) chiral Schiff base metal complexes. This review was compiled for the purpose of deepening the understanding of the induced CD phenomenon.
