Outline of Final Research Achievements

In this study, BDA-Azo-polyamide acid gels were synthesized by terminal cross-linking of azobenzene-incorporated tetrafunctional amines with acid anhydrides to form a homogeneous network structure. The photo-flexing behavior of the polymer gels was analyzed; the imidization of BDA-Azo-polyamide acid gels resulted in a bending speed of about 1 s. Gels with dispersed fluorescent microbeads were prepared, and the movement of the beads before and after light irradiation was observed using a multiphoton confocal laser microscope. By tracing the fluorescent beads after light irradiation, the bending behavior of the photoresponsive gel is expected to be as follows: (1) the part inside the UV light irradiation area shrinks and enters the inner direction of the gel, (2) the force by the mesh shrinkage propagates and pulls the mesh from outside of the irradiation area in parallel, and (3) the mechanism of bending using the part inside the irradiation frame as a fulcrum.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発したBDA-Azo-PIゲルは、光に対して協同運動的に収縮または膨潤し、どんなに小さくしても、その挙動は変わらないことから、分子レベルの大きさのマイクロマシンへの応用が可能である。光照射部位での変形がトリガーとなり、その外部まで協同運動が起こる現象が見つかったのは世界で初めてである。ゲルの光照射による収縮の際には、内部に含んだ溶媒を排出し、膨潤の際には、内部に溶媒を取り込むので、光で駆動するマイクロポンプとして機能させることができる。その突出量は現在のインクジェットプリンターを遙かに凌駕するアトリットルを実現させることが可能である。
