Functions like optical switching and memory by non-linear optical effects, all depending on light intensity, are expected to result in realization of a pivotal optical device in optical computing. This is a new data processing system that makes the maximum use of light characteristics such as parallel and spatial processing capabilities and high speed. Organic compounds with delocalized conjugated p-electrons have gained much attention because of their large non-linear optical properties and quick response. The Institute discovered the excellent non-linear optical properties of polydiacetylene and one-dimensional metal complexes. Studies for synthesis and the discovery of these new compounds are moving forward focusing on the correlation between molecular structure and optical characteristics, with support from molecular design programs, structural analysis by x-ray diffraction, and solid-state high-resolution NMR.
