Molecular Interactions and Supramolecular Photochirogenesis

In our studies on (1) asymmetric photoreaction with chiral sensitizers, (2) supramolecular asymmetric photochemistry using chiral hosts such as modified zeolite, cyclodextrin, proteins, and nucleic acids, and (3) the relevant thermodynamic work on supramolecular systems, we have demonstrated for the first time that the entropy related factors such as temperature, pressure, and solvation, play decisive roles particularly in molecular recognition and chiral photoreactions, where weak molecular interactions, including hydrogen bonding, dipole-dipole, van der Waals, and hydrophobic interactions, simultaneously operate in a concerted manner. We pursue the possibility and feasibility of general reaction/equilibrium control by entropy-related factors with the aid of experiment and theory.
