Abstract Stimuli‐responsive fluorescent hydrogels are three‐dimensional networked polymeric materials with tunable luminescence and dynamic properties, which play an important role as a water‐rich soft material in the fields of information encryption, bionic actuation, bioimaging, environmental monitoring, luminescent materials. Compared conventional hydrogels, their unique properties allow visualization microscopic dynamics within polymer network. By rational inclusion motifs, such photoswitches, AIEgens, lanthanide complexes, host–guest these endowed tunability emission, shape, phase time space response to effectors. In this review, we summarize fabrication strategies that mainly used by recently reported stimuli‐responsive applications

Abstract Conductive polymer hydrogels (CPHs) are gaining considerable attention in developing wearable electronics due to their unique combination of high conductivity and softness. However, the absence interactions, incompatibility between hydrophobic conductive polymers (CPs) hydrophilic networks gives rise inadequate bonding CPs hydrogel matrices, thereby significantly impairing mechanical electrical properties CPHs constraining utility electronic sensors. Therefore, endow with good performance, it is necessary ensure a stable robust network CPs. Encouragingly, recent research has demonstrated that incorporating supramolecular interactions into enhances interaction, improving overall CPH performance. comprehensive review focusing on (SCPH) for sensing applications currently lacking. This provides summary typical strategies employed development high‐performance elucidates SCPHs closely associated Moreover, discusses fabrication methods classification SCPH sensors, while also exploring latest application scenarios Finally, challenges sensors offers suggestions future advancements.

A multifunctional supramolecular assembly, comprising nor-seco-cucurbit[10]uril (ns-Q[10]) and tripyridine-bridged 4-(4-bromophenyl)pyridine (BTPY), has been constructed. The host–guest interaction between BTPY ns-Q[10] resulted in a decrease the singlet–triplet splitting energy (ΔEST), thereby enhancing intersystem crossing process. Furthermore, multiple hydrogen bonding interactions BTPY@ns-Q[10] assembly poly(vinyl alcohol) (PVA), as well its own interaction, inhibited nonradiative transitions, resulting long-lived room temperature phosphorescence (RTP) (τ = 261.3 ms). This RTP material provided potential method for constructing materials information encryption anticounterfeiting through strategy. Moreover, terpyridine component of BTPY, known strong metal coordination ability, enables to rapidly detect Fe2+ Fe3+ ions aqueous solution.

Supramolecular polymers offer promising potential for enhanced oil recovery (EOR) advancing techniques. Current instrumental analyses face limitations in capturing instantaneous intracomplex motions due to temporal and spatial constraints. The molecular mechanism of supramolecular polymer transport behavior within nanoconfinement is not yet fully understood. Therefore, the self-assembly β-cyclodextrin (β-CD) adamantane (ADA)-modified (p-AA-β-CD-ADA) was delved into this work. Further exploration focuses on translocation dynamics p-AA-β-CD-ADA under external driving forces. Results suggest that β-CD ADA were assembled nodes form a host guest, combining with "node–rebar–cement" interaction model encapsulating formation these polymers. heightened density hydrate layers at nanoscale pore throats acts as constraining factor, resulting restricted mobility altered During passage through nanopore throats, host–guest molecules experience noncovalent dissociation. Notably, exhibit remarkable self-healing capabilities, reinstating their assembly state upon traversing throats. This work provides molecular-level comprehension utility EOR processes, offering valuable information design employed low-permeability reservoirs.
