本年度は、自身が筆頭著者となる論文3報を論文化することができた。まず、ジアリールエテン結晶の光誘起結晶成長を用いたバイオミメティック材料の開発に関して、二つのジアリールエテンを混合することで、テングシロアリの翅の表面構造とその機能を再現することに成功した。この機能は、雨を弾き、霧を集める機能を有していることから、霧から水を創る技術に応用することが期待されている。この研究に関しては、Commun. Chem. 誌にて論文が掲載された。また、ハスの葉の超撥水性の起源であるダブルラフネス構造をジアリールエテン結晶の光誘起結晶成長を用いて再現し、そのサイズ、間隔などを精密にコントロールすることで、より水滴を弾く表面の作製に成功した。この結晶成長技術は、複雑な表面形状を制御することが可能な技術であり、固体表面の濡れ性の制御や、フォトニック結晶材料への応用が期待されている。この研究に関しては、Langmuir誌にて論文が掲載され、バックカバーにも採用された。また、ジアリールエテン結晶の光誘起屈曲現象を用いた物質輸送表面に関しては、光で屈曲する板状のジアリールエテン結晶が無数に成長した表面上にポリスチレンビーズをのせ、紫外光照射方向を変えることによる、物体を意図した方向へ輸送するシステムを開発することに成功した。この研究は、フォトクロミック結晶を用いた、光照射のみで駆動するソフトロボットとしての応用が期待されている。この研究に関しては、Angew. Chem. Int. Ed.誌にて論文が掲載され、バックカバーにも採用された。

We have newly synthesized a hollow crystal showing photosalient phenomena in which crystals are broken by light irradiation. Then, we poured fluorescent substances into the hollow to show its effectiveness. By UV light irradiation to the hollow crystal, we found the substances were released with breaking the crystal. To elucidate the mechanism of salient phenomena, we synthesized diarylethene derivatives whose molecular structures were similar to each other and compared the light response of their crystals. The difference between the orientation of the molecules in the crystals induced the difference in direction of photoinduced strain, which results in the different manner of breaking of the crystals. In addition, needle crystals that are bent by light irradiation were arranged side by side on the surface of the substrate, and the needle crystals were bent in a coordinated manner by the light irradiation. This system worked for moving an object on the surface.
