In contrast to the self-assembly of homosupramolecules, the self-assembly of heterosupramolecules is more challenging and significant in various fields. Herein, we design and investigate a cucurbit[8]uril-mediated heterodimerisation based on an arene-fluoroarene strategy. Furthermore, the heteroternary complex is found to be able to undergo a photoinduced [2+2] heterocycloaddition, resulting in the formation of an unexpected [2]rotaxane. This work demonstrates a novel supramolecular heterodimerisation system that not only contributes to the development of photoisomerisation systems, but also enriches synthetic methods for mechanically interlocked molecules.
We have investigated an approach to determine the Majorana type-phases using the time evolution of lepton family numbers. The Majorana type-phases are related to the orientation of unitarity triangles for the Pontecor...

Responsive organic luminescent aggregates have a wide range of application fields, but currently there is still a lack of reasonable molecular design strategies. Introducing ion-π interactions into molecules can effectively alter their luminescent properties. However, current research typically focuses on ion localization at luminescent conjugated groups with the strong interaction forces. In this work, we introduce the flexible alkoxy chain spacers between fluorescent conjugated groups and ion-π interaction sites, and then adjust the fluorescence performance of the molecule by changing the strength of ion-π interactions. Bromine ion-based molecules with strong ion-π interactions exhibit high and stable fluorescence quantum yields in crystals and amorphous powders under the external stimuli. Hexafluorophosphate ion-based molecules with weak ion-π interactions have the high fluorescence quantum yield in crystals and very low fluorescence quantum yield in amorphous powders, showing variable fluorescence intensities under external stimuli. This demonstrates a new class of responsive organic luminescent solid-state materials.
Absorption rates for traditional adsorbents were predominately determined by the concentration gradient from bulk to absorbents and surface area. A novel sandwich-structured capacitor (SSC) containing adsorbents is de...

We investigate the third-order nonlinear optical properties of silver nanocubes (Ag-NCs) and Ag@Au hollow nanostructures using femtosecond Z-scan measurements at 1040 nm. Both systems exhibit negative nonlinear refraction ( n 2 ∼10 −16 cm²/W) attributed to hot-electron generation under ultrafast excitation. In contrast, saturable absorption (SA) is uniquely observed in Ag@Au nanoboxes, with SA intensity tunable via Au content. Ag@Au hollow nanostructures exhibit an order-of-magnitude enhancement in nonlinear refractive index ( n 2 ) and saturable absorption (SA) performance compared to monometallic Ag nanocubes, highlighting morphology and composition as key design parameters. These results demonstrate the promise of Ag@Au hollow nanostructures for applications in ultrafast all‑optical switching and nonlinear photonic devices.
