Abstract The rapid advancement in attractive platforms such as biomedicine and human‐machine interaction has generated urgent demands for intelligent materials with high strength, flexibility, self‐healing capabilities. However, existing ability are challenged by a trade‐off between low elastic modulus, healing due to the inherent strength of noncovalent bonding. Here, drawing inspiration from human fibroblasts, monomer trapping synthesis strategy is presented based on dissociation reconfiguration amphiphilic ionic restrictors (7000‐times volume trapping) develop eutectogel. Benefiting nanoconfinement dynamic interfacial interactions, molecular chain backbone formed confined domains mechanically reinforced while preserving soft movement resulting eutectogels demonstrate superior mechanical properties (1799% 2753% higher tensile toughness than pure polymerized deep eutectic solvent), excellent efficiency (>90%), tangential modulus (0.367 MPa during working stage), sensitively monitor activities. This poised offer new perspective developing wearable electronics tailored body motion.

Abstract Compared to conventional gels, eutectogels encompassing deep eutectic solvents (DESs) circumvent the shortboards including poor temperature resistance, high cost, and undesired toxicity. However, existing suffer weak intra‐ interchain interactions, which culminates in vanishing autofluorescence, mechanic feeble adhesion. Although myriad strategies have been proposed boost polymer/polymer interactions within processes are time‐consuming, not suitable for mass production or emergent deployment. Herein, deal with it, a facile solvation chemistry is leveraged build dynamic rigid network via incorporating active polymer backbones DESs. Within these eutectogels, DESs play magnet‐like role, physically cluster chains together multiple noncovalent forces, thus intensifying DESs/polymer interactions. This bestows rare autofluorescence unprecedentedly strength, toughness, adhesion among reported analogues, even harsh conditions. Moreover, mechanism of fully scrutinized first time. It believed that this strategy can be easily expanded orchestrations other soft materials.

Abstract The powerful capability of multi‐stimulus‐responsive fluorescent hydrogen‐bonded organic frameworks (HOFs) to respond external chemical or physical stimuli in various manners makes them appealing advanced information encryption. However, it is still a global challenge manipulate the fluorescence properties finely achieve dynamic time dimension. Here, feasible strategy shown control emission materials by introducing common SP photochromic compound (1′, 3′, 3′‐trimethyl‐6‐nitro‐spiro‐ [chromene‐2, 2′‐indoline]) into functionalized HOFs, properties. Two kinds HOFs are successfully synthesized modifying unbonded carboxylic group with Tb 3+ 5‐hexene‐1‐ol termed Tb‐HOFs and HOF‐olefin, respectively. Then, spiropyran loaded HOFs‐olefin can be well controlled changing lanthanide dopants light stimulation time. Relying on emission, multilevel encryption including anti‐counterfeiting ink, QR code, base time‐resolved storage has been demonstrated, security level greatly improved. This work opens an avenue for achieving technology, where “time factor” equivalent key, which introduces countless unpredictable possibilities imitation more challenging.
