Supramolecular Science Laboratory
Chief Scientist: Katsumi MIDORIKAWA (D.Eng.)
Optical and electronic properties of supramolecular systems such as hyper branched polymers, dendrimers and cyclic oligomers are studied from the viewpoint of energy states and topological structures. In addition to the fundamental understandings of structure-property-relationship, applications to optical information processing and soft-optoelectronics devices are important targets of the research. For the development of switchable soft-optoelectronics materials, changes of the electronic state with molecular recognition, the self-tuning mechanism of supramolecules and collective motion based on molecular-structural changes are characterized using nonlinear optical spectroscopy. Spatial light modulators and hologram display devices are also developed based on photoinduced refractive index changes.
