Outline of Final Research Achievements |
A series of novel methodologies to create static or dynamic asymmetric structures by taking advantage of self-assembly have been developed. The representative research topics are the following : (1) Near-infrared vapochromism of chiral metal complexes, (2) Two-dimensional nanosheet formation of metal oxide clusters with macroscopic anisotropy, and development of optical drawing techniques based on photoinduced electron transfer at the interface, (3) Discovery of interface effects in the electric field orientation of polar organic molecules confined in nanofiber interstitial spaces of supramolecular organogels, and (4) Discovery of self-organized asymmetric organization of photofunctional molecules and switching of nonlinear optical functions.
