Electrocatalytic C-N coupling from carbon dioxide and nitrate provides a sustainable alternative to the conventional energy-intensive urea synthetic protocol, enabling wastes upgrading value-added products synthesis. The design of efficient stable electrocatalysts is vital promote development electrocatalytic In this work, copper phthalocyanine (CuPc) adopted as modeling catalyst toward synthesis owing its accurate adjustable active configurations. Combining experimental theoretical studies,...
Novel main-chain liquid crystalline Diels-Alder dynamic networks (LCDANs) were prepared that exhibit unprecedented ease for actuator programming and reprocessing compared to existing network (LCN) systems. Following cooling from 125 °C, LCDANs are deformed with aligned mesogens self-locked at room temperature by slowly formed (DA) bonds, which allows the formation of solid 3D actuators capable reversible shape change, strip walker wheel-capable light-driven locomotion upon either thermally...
A Cu(<sc>ii</sc>) metal–organic framework (MOF) was used directly as an electrochemical biosensor. It exhibited excellent stability and selectivity towards ascorbic acid in a bio-mimic environment containing mixture of amino acids.
To realize the sustained release and long-term intratumoural retention of water-soluble cisplatin, thermo/pH-sensitive cisplatin-directed coordination-crosslinking nanogels (Pt-PNA) were developed via coordination bonds Pt–carboxyl groups. As ratio (CR) increased from 5% to 35%, sizes Pt-PNA decreased 999 nm 167 nm, their zeta potentials −35 mV −13 mV. Only through a simple mixing cisplatin PNAs, entrapment efficiencies (EEs) reached near 100% (>90%), drug-loading amounts (DLs) could achieve...

Abstract Liquid crystalline elastomers (LCEs) have been actively investigated as stimuli‐controlled actuators and soft robots. The basis of these applications is the ability LCEs to undergo a reversible shape change upon liquid (LC)‐isotropic phase transition. Herein, we report synthesis novel LCE based on side‐chain polymer (SCLCP). In contrast known LCEs, this exhibits striking anomalous change. Subjecting mechanically stretched monodomain strip LC‐disorder transition, both length width...
<title>Abstract</title> High value-added azobenzene liquid crystal elastomers (AZO-LCEs) derived from styrene-butadiene-styrene triblock copolymer (SBS) are herein developed. The glassy polystyrene (PS) domains in SBS that spontaneously separate LCEs can provide the self-supporting template during actuation and lock LC orientation, enabling reprogrammable, reshapable recyclable AZO-LCE actuators. decoupling effect between oriented continuous polybutadiene (PB) phase leads to arrangement of...

By investigating the relationship between and of polymer chains, desired can likely be synthesized. In this study, a series copolymers 1,1‐diphenylethylene (DPE) derivatives styrene derivatives, which exhibit nontraditional intrinsic luminescence (NTIL), synthesized using living anionic polymerization. changing...
Existing polymer materials often lack the ability to dynamically adjust lubrication in response external stimuli. This gap adaptable technology limits their application advanced systems such as intelligent motion devices and soft robotics. To address this challenge, a dual-responsive lubricating hydrogel is introduced designed with thermal shear-responsive supramolecular network integrated into stable framework. The exhibits partial gel-sol transition under or shear stress, mimicking mucus...
Multifunctional hydrogels have garnered significant interest but remain challenging due to the complex preparation process and high cost of raw materials. Herein, bisphenol A diglycidyl ether (BADGE) poly(ethylene glycol) (PEGDGE) were reacted with 3-amino-1-propanol via a catalyst-free amine–epoxy "click" chemistry, followed by addition hydrophilic 1,3-propane sultone (1,3-PS) higher water content, then cross-linked hexamethylene diisocyanate (HDI) in one-pot provide polymer network, i.e.,...
A new Tb(<sc>iii</sc>)–NITR complex was obtained, which showed a 1D zig-zag chain structure and field-induced dual relaxation processes.
A porous liquid-crystalline network (LCN), prepared by using a template method, was found to exhibit peculiar actuation functions. The creation of porosity makes the initially hydrophobic LCN behave like hydrogel, capable absorbing large volume water (up ten times sample size LCN). When amount absorbed is relatively small (about 100 % swelling ratio), displays anisotropic in and, same time, retained uniaxial alignment mesogens ensures thermally induced shape change associated with...
