A unidirectional light-driven rotary motor was looped in a figure-of-eight molecule by linking two polymer chains between its stator and rotor parts. By properly tuning the size of these linkers, clockwise rotation under UV light shown to create conformationally strained twists chains, this tensed conformation, energy stored molecular object sufficient trigger reverse back fully relaxed state. The functioning principle motorized device appears very similar that macroscopic whirligig crafts...
A hetero[6]rotaxane bearing three different kinds of macrocycle is designed and successfully synthesized through a one-pot “click” reaction by employing facile efficient integrative self-sorting principle.
Modulation of electronic spin states in cobalt-based catalysts is an effective strategy for molecule activations. Crystalline-amorphous interfaces often exhibit unique catalytic properties due to disruptions long-range order and alterations structure. However, the mechanisms activation at remain elusive. Herein, we present a Co3O4 spinel-based catalyst featuring crystalline-amorphous interfaces. Characterization analyses confirm that tetrahedral Co2+ selectively etched from bulk spinel,...
Abstract Layered oxides store and release energy through the insertion extraction of Li‐ions, diffusion rate Li‐ions within these directly affects charging discharging rates Li‐ion batteries. Unlike previous approaches that focus on improving battery performance by reducing size active particles, this study synthesizes layered metal with Mg embedded in () crystal facts (ACFTs), which feature an unsaturated coordination structure. This unique structure facilitates reversible large quantities...
Designing artificial molecular machines to execute complex mechanical tasks, like coupling rotation and translation accomplish transmission of motion, continues provide important challenges. Herein, we demonstrated a novel machine comprising second-generation light-driven motor bistable [1]rotaxane unit. The can rotate successfully even in an interlocked system through photoinduced cis-to-trans isomerization thermal helix inversion, resulting concomitant transitional motion the [1]rotaxane....
The successful triggering of ring-shuttling motion between two stations in a [2]rotaxane is demonstrated by employing photochemical bond-cleavage strategy. A photolabile bulk barrier covalently introduced into identical the thread to prevent dynamic shuttling macrocycle, resulting "gated" state. Irradiation UV light (λ = 365 nm) results complete removal and balanced indicating an "open" state rotaxane. In addition, process from rotaxane was executed chemical-rebonding method.
An acid/base responsive amphiphilic [2]rotaxane switch containing a hydrophilic macrocycle component and hydrophobic terminal bulky group was prepared characterized. The morphology of the supramolecular assemblies formed by rotaxanes could be switched between spherical vesicles worm-like micelles using stimuli, as confirmed transmission electron microscopy (TEM).
Well-defined supramolecular helical nanofibers have been constructed by a rationally designed achiral monomer in aqueous solution based on the 1:2 host-guest combination between cucurbit[8]uril and 4,4'-bipyridin-1-ium chloride (BPY+ ) salt derivative. The formed nanostructures could be adjusted varying concentration of from to pH-responsive hydrogel.
A novel braided hetero[2](3)rotaxane is demonstrated by integrating the structure and mechanically interlocked rotaxane, in which a heterotritopic linear tris(dialkylammonium) guest penetrates tris(crown ether) host, resulting formation of pseudohetero[2](3)rotaxane with different crossing threading points. Then constructed through "CuAAC" click reaction.
The structural complexity of mechanically interlocked molecules are very attractive to chemists owing the challenges they present. In this article, novel with a daisy-chain-containing hetero[4]rotaxane motif were efficiently synthesized. addition, integrative self-sorting strategy is demonstrated, involving an ABB-type (A for host, dibenzo-24-crown-8 (DB24C8), and B guest, ammonium salt sites) monomer macrocycle benzo-21-crown-7 (B21C7), in which assembled species hydrogen-bonding-supported...
The integration of molecular machines and motors into materials represents a promising avenue for creating dynamic functional systems, with potential applications in soft robotics or reconfigurable biomaterials. However, the development truly scalable controllable approaches incorporating polymeric matrices has remained challenge.

The role of sulphuric acid (H 2 SO 4 ) in fabrication graphene oxide besides as intercalant has not been well addressed. In this work, Raman spectroscopy is used to monitor structural evolution chemical vapor deposition (CVD) chemically oxidized by dilute H . From the analysis spectra graphene, we propose that oxidation first initiates at preexisting defects, and vacancy‐like defects are formed. Following radial growth vacancy, pits appear graphene. This assumption further confirmed atomic...
