Outline of Final Research Achievements |
We investigated photoinduced deformation of crosslinked photochromic liquid-crystalline polymers under cryogenic conditions in relation to molecular structures. On photoirradiation under vacuum, photothermal effects were found to play significant roles in deformation of films. Adequate design of liquid-crystalline monomers allowed photoinduced deformation of the films even in liquid nitrogen, which prevents the rise in temperature.

Academic Significance and Societal Importance of the Research Achievements |
架橋フォトクロミック液晶高分子は新規アクチュエーター材料としての実用化が期待されている。本研究で探究した極低温における変形誘起は,当該材料の宇宙空間等の特殊環境における利用可能性を示すものである。さらに従来の熱運動とは異なる「光運動」という新たな運動様式を精査することにより,高分子鎖の運動性という高分子科学にとって最も本質的な問題について新たな知見を見出した。
