| Outline of Final Research Achievements |
By applying the preparation procedure of supramolecular ion gels as nonvolatile physical gels, protic ionic liquids were infiltrated into diblock copolymer thin films bearing proton acceptor functional groups (pyridyl groups) by a drive force of hydrogen bonding, which provided nonvolatile (supramolecular) photonic swollen gel films. The inner structures of photonic gel films were observed by electron microscopy and ultra-small angle X-ray scattering, and photonic crystal properties (reflectance properties) were also investigated. Furthermore, the wavelength of reflected light and the swelling ratio were controlled by using ionic liquid mixture. Reflectance property control by acid addition, temperature variation, and electric field application was also achieved.
