Summary: Here we report light-activated convertible pseudorotaxanes (PRs) that can self-assemble and show tunable fluorescence, enabling deformable nano-assemblies. When exposed to light, a specific combination of molecules transform into a transient form, which can thermally relax to its original form in the dark, accompanied by periodic fluorescence changes. The self-assembly of these PRs leads to the formation of octahedral and spherical nanoparticles, which can be used for dynamic imaging of the Golgi apparatus.

Summary: This study demonstrates the photo-tuning amphiphilicity in Pickering emulsions using beta-cyclodextrin-grafted alginate and azobenzene derivative supramolecular self-assemblies as photoactivatable emulsifiers. By employing the photoisomerization of a host-guest system, the polarity of the microenvironment can be tailored, resulting in reversible variation of hydrophilic/hydrophobic balance and oil-water separation in Pickering emulsions with external UV irradiation. This provides a sustainable and eco-friendly formulation for the fabrication of stimuli-responsive Pickering emulsions.

Summary: This study focuses on a series of luminescent liquid crystal elastomers with photo-induced deformation behavior and photo-responsive fluorescence. By adjusting the crosslinking agent content, the deformation rate and maximum bending angle of the polymers can be controlled. All prepared LCEs exhibit aggregation-induced emission enhancement (AIEE) characteristic and emit strong fluorescence in solid state.

Summary: We have demonstrated the fabrication of dual-responsive (thermo/light) chiral plasmonic films by using photoswitchable achiral liquid crystal (LCs) for templating helical assemblies of Au NPs. The chiroptical properties of the organic and inorganic components were confirmed by circular dichroism spectroscopy (CD), with a dissymmetry factor (g-factor) of up to 0.2. The controlled melting of organic nanotubes and/or inorganic nanohelices can be achieved by exposing the material to UV light and can be reversed using visible light, with the chiroptical response further modified by varying the temperature.

Summary: The article describes a method for remotely manipulating non-photoresponsive chiral plasmonic molecules (CPMs) using light, inducing DNA triplex link formation through a photoacid medium, resulting in spatial reconfiguration of CPMs. The overall chirality change depends on the fraction of CPMs undergoing reconfiguration, which is related to the intensity of incident light.

Summary: Charge transfer interactions are commonly used in constructing supramolecular systems, but the formation of CT complexes at the liquid-liquid interface has not been reported until now. By utilizing electron-deficient acceptors in water and electron-rich donors in oil, CT complex surfactants can be formed and assembled at the oil-water interface, ultimately leading to the creation of higher-order nanofilms with exceptional mechanical properties. The redox-responsiveness of the electron-deficient acceptor allows for reversible manipulation of the assembly and disassembly of CTCSs, offering the potential for switchable structures in liquids.

Summary: This study discovered the synergistic effects between liquid crystal and crystalline phase, and successfully introduced azobenzene molecules into polyurethane elastomers to prepare azobenzene liquid-crystal elastomers (ALCEs). The synthetic ALCEs can utilize the reversible isomerism capability of azobenzene molecules to achieve large macroscopic deformation under light irradiation. Compared to traditional azobenzene materials, the ALCEs exhibit higher bending speed and recovery rate.

Summary: The photo-crosslinkable hydrogel derived from cinnamoyl modified alginate shows potential as an efficient drug carrier with the ability to control drug release. The gel can be crosslinked without the need for initiators through UV exposure, and the extent of crosslinking can be adjusted through cinnamoyl functionalization or UV light exposure time.
