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.

UV-Vis Higher-Order Derivative Spectra Disclose the Involvement of Two Processes in the Solid-State 4+4 Photocycloaddition of an Amorphous Bisanthracene

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.

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.
