I try to create organic
crystal devices as electronics and photonics
materials that can photoreversibly change
crystal shape, electric conductivity,
fluorescence property, and refractive index,
etc. I control crystal structures and the size
of the crystals of photochromic crystals that
cause photoreversible molecular structure
changes, and also control solid state properties
of their organic photochromic crystals by
photoirradiation. These materials can be
potentially applied for novel organic devices,
and it is possible not only to become a new
organic device but also to open a new
possibility as the crystal materials.
