CONSPECTUS: Supramolecular gels are ideal candidates for soft, stimuli-responsive materials, because they combine the elastic behavior of solids with microviscous properties fluids. The dynamic networks fibers in supramolecular reminiscent cytoskeleton a cell and provide scaffolds to implement function. When made responsive stimuli, these mechanical can be controlled. Gel-sol transitions also open opportunities immobilize molecules inside gel's cavities release them on demand. To establish...
Although the concept of structural water that is bound inside hydrophobic pockets and helps to stabilize protein structures well established, has rarely found a similar role in supramolecular polymers. Water often used as solvent for polymerization, however without taking comonomer polymer structure. We report low-molecular weight monomer whose polymerization triggered by incorporation water. The presence molecules comonomers essential process. polymeric material exhibits strong adhesion...
Supramolecular polymerization for non-wetting surface coatings is described. The self-assembly of low-molecular-weight gelators (LMWGs) with perfluorinated side chains can be utilized to rapidly construct superhydrophobic, as well liquid-infused slippery surfaces within minutes. lubricated exhibits impressive repellency biological liquids, such human serum and blood, very fast self-healing. As a service our authors readers, this journal provides supporting information supplied by the...
A quite simple, achiral benzo-21-crown-7-substituted bis(urea) low-molecular weight gelator hierarchically assembles into helical fibrils, which further develop bundles and finally form a stable gel in acetonitrile. The gel–sol transition can be controlled by three different molecular recognition events: K+ binding to the crown ethers, pseudorotaxane formation with secondary ammonium ions Cl− urea units. Addition of cryptand that scavenges Ag+ addition remove chloride bases/acids, mediate...
A supramolecular carbohydrate-functionalized two-dimensional (2D) surface was designed and synthesized by decorating thermally reduced graphene sheets with multivalent sugar ligands. The formation of host-guest inclusions on the carbon provides a versatile strategy, not only to increase intrinsic water solubility graphene-based materials, but more importantly let desired biofunctional binding groups bind surface. Combining vital recognition role carbohydrates unique 2D large flexible area...
We have developed a new type of surface-enhanced Raman scattering (SERS) substrate that consists per-6-deoxy-(6-thio)-beta-cyclodextrin (CD-SH) modified by silver nanoparticles (AgNPs) for sensing polycyclic aromatic hydrocarbons (PAHs), kind environmental pollutant, with very low affinity to metallic surfaces. The designed system can induce some PAH molecules (anthracene and pyrene) insert into the hydrophobic cavity beta-CD, which enables one detect SERS PAHs because analytes are close...
Partner preferences in pseudorotaxane formation were exploited to establish an integrative self-sorting system able discriminate simultaneously at the sequence and stereochemical level (see picture). It was found that calix[6]arenes threaded selectively with a preferred orientation onto bisammonium axles, even when structural differences between possible building blocks small located remote from binding sites.
In cooperative catalysis, the combination of chemo- and biocatalysts to perform one-pot reactions is a powerful tool for improvement chemical synthesis.

Abstract Plant chloroplasts have a highly compartmentalized interior, essential for executing photocatalytic functions. However, the construction of reaction compartment similar to in inorganic–biological hybrid systems (IBS) has not been reported. Drawing inspiration from chloroplast and phenomenon liquid–liquid phase separation, herein, new strategy is first developed constructing subcellular system through separation technology living cells. Photosensitizers vivo expressed hydrogenases...
Sunlight-driven hydrogen production provides a sustainable solution for clean energy generation. Despite their potential, extracellular photosensitized biohybrid systems are typically hindered by sluggish electron transfer between semiconductor materials and microorganisms. Herein, we introduce bioinspired development, the membrane-anchoring protein approach, to overcome this limitation. Using incorporated with TiO2 binding peptide on engineered E. coli, establish proof-of-concept...

To advance the exploration of mechanisms underlying natural multi-gated ion channels, a novel butterfly-shaped biomimetic K+ channel GnC7 (n = 3, 4) is developed with dual mechanical and pH responsiveness, exhibiting unprecedented K+/Na+ selectivity (G3C7: 34.4; G4C7: 41.3). These channels constructed from poly(propylene imine) dendrimer benzo-21-crown-7-ethers achieve high transport activity (EC50: 0.72 µm for G3C7; 0.9 G4C7) due to their arc-like rotation. The dynamic mode relies on...
