Photoresponsive supramolecular polymers are well-organized assemblies based on highly oriented and reversible noncovalent interactions containing photosensitive molecules as (co-)monomers. They have attracted increasing interest in smart materials dynamic systems with precisely controllable functions, such light-driven soft actuators, photoresponsive fluorescent anticounterfeiting light-triggered electronic devices. The present review discusses light-activated used their main photo-induced changes, e.g., geometry, dipole moment, chirality. Based these distinct formed by exhibit disassembly reassembly. As a consequence, polymerization, "depolymerization," regulation of the lengths topologies observed. Moreover, light-controlled functions polymers, actuation, emission, chirality transfer along length scales, highlighted. Furthermore, perspective challenges future opportunities is presented. Besides challenge moving from harmful UV light to visible/near IR avoiding fatigue, enabling biomedical applications, include actuators helical motion, light-modulated information transmission, optically recyclable materials, multi-stimuli-responsive systems.

Low-molecular-weight adhesives (LMWAs) possess many unique features compared to polymer adhesives. However, fabricating LMWAs with adhesion strengths higher than those of polymeric materials is a significant challenge, mainly because the relatively weak and unbalanced cohesion interfacial adhesion. Herein, an ionic liquid (IL)-based adhesive high strength demonstrated by introducing IL moiety into Y-shaped molecule replete hydrogen bonding (H-bonding) interactions. The moieties not only destroyed rigid ordered H-bonding networks, releasing more free groups form bonds (H-bonds) at substrate/adhesive interface, but also provided electrostatic interactions that improved energy. synthesized IL-based adhesive, Tri-HT, could directly thin coatings on various substrates, up 12.20 MPa. Advanced electrical conductivity, self-healing behavior, electrically-controlled be fabricated combining Tri-HT carbon nanotubes.

Stimuli-responsive hydrogels with programmable shape changes are promising materials for soft robots, four-dimensional printing, biomedical devices and artificial intelligence systems. However, these applications require the fabrication of complex, heterogeneous reconfigurable structures customizable functions.
