基板表面の一分子層のフォトクロミック反応で数µm厚のネマチック液晶層の分子配向変化を誘起できる (コマンドサーフェス) 。この現象の本質的理解のために，コマンドサーフェス/液晶層界面のモデル系を構築し，その光応答特性を検討した。側鎖にアゾベンゼンの有する両親媒性高分子と液晶分子の水面混合膜からのLB膜作製をし，その構造評価を行った。紫外および可視光に対する光応答特性について紫外可視および赤外分光法を用いて検討を行い，アゾベンゼン分子の光応答による分子協調的な液晶分子の配向変化について明らかにした。

<p>A new dipeptide with an acridone chromophore, namely 2-acridonylalanine-phenylalanine (AAP) was synthesized, and a fluorescent hydrogel was produced under physiological pH conditions by the AAP self-assembly process. The hydrogel exhibited a blue emission and reasonable thermoresponsiveness. Therefore, dipeptides containing an acridone side chain of the first residue were found to be effective hydrogelators.</p>
UV-Vis Higher-Order Derivative Spectra Disclose the Involvement of Two Processes in the Solid-State 4+4 Photocycloaddition of an Amorphous Bisanthracene

<p>UV-induced solid-state oligomerization of an amorphous bisanthracene in films was determined by UV-Vis even-order derivative spectra to reveal the involvement of fast and slow photocycloaddition processes due to the difference in the level of π,π-interactions and the marked enhancement of the photoreaction above glass transition temperature.</p>
Unconventional Approaches to Light-Promoted Dynamic Surface Morphing on Polymer Films

<p>Recent progress in research of light-promoted surface morphing on polymer materials is reviewed. Photoinduced mass transport motions in azobenzene polymers leading to surface relief gratings (widely called SRGs) formation are well-known and extensively discussed. Among many efforts, this article focuses on unconventional approaches, most of which are seemingly less highlighted. The first part introduces investigations using azobenzene polymers; introducing supramolecular approaches with tunable and removable azobenzene units, self-structuring of surface morphology upon single laser beam irradiation, photo-triggered migration via Marangoni flow, SRG formation and other functions of polymer brushes etc. The second part overviews the mass transport motions driven by other photoreaction classes such as photopolymerization, photocrosslinking, and photoisomerization of non-azobenzene components. The final part describes new dynamic surface morphing processes observed in fingerprint texture of liquid crystals and liquid crystal polymer networks, which can be applied to reversible friction control and self-cleaning. These uncommon attempts at photo-assisted dynamic morphing extend the possibilities of microfabrication on polymer films and are expected to find new opportunities to create new surface functions in soft materials.</p>
