| Research Abstract |
Cyclodextrins (CD) are cyclic oligosaccharides consisting of six or more D-glucopyranose units, the interior of which forms a hydrophobic cavity. CDs are well-known in their ability to form inclusion complexes with hydrophobic molecules in aqueous solution and a number of studies have been performed about photochemical properties of various guests in the CD nanocavities. In this research, we employed the CD confinement effects as a tool to suppress an electronic decoherence of the guest wavefunction by reducing intermolecular interactions between a guest molecule and the surrounding environment. Decoherence suppression was observed as a spectral narrowing of the electronic transitions of the guests in the frequency domain or as a quantum interference signal in the time domain.
