Summary: In this study, a series of linear cyanostilbene gelators with a pyridine moiety and different lengths of alkoxyl group were designed. The gels showed responsiveness to temperature, light, and organic acid/base, and their fluorescence intensity and color could be reversibly changed during the gel-sol transitions. Furthermore, a thin film based on the CSpy-C8 xerogel was prepared and utilized as a multi-stimuli-responsive fluorescence display for information storage and anti-counterfeiting.

Summary: It is challenging to construct multifunctional chiral stimulus-responsive molecules and modulation of their nanoscale morphology. In this paper, a novel chiral molecule with photoactive and potentially bioactive properties was synthesized. The morphological changes of its self-assembly were influenced by solvent polarity and light exposure. The synthesized molecule underwent efficient Z-E isomerization under light irradiation by introducing highly oriented hydrogen bonds into the cyanostilbene part. The resulting morphological changes from nanohelices to vesicles with chiroptical evolution provide a green and efficient method for designing responsive chiral materials.

Summary: A novel series of cyanostilbene-based hexacatenar mesogens were synthesized through Suzuki coupling and Knoevenagel reactions. These compounds exhibited liquid crystalline behavior and showed solvatochromism and aggregation-induced enhanced emission (AIEE) due to their non-planar structure and long π-conjugated core. The introduction of different functional building blocks also enabled reversible changes in fluorescence properties induced by temperature and volatile acids.

Summary: In this study, a highly fluorescent zero-dimensional nano-ring supramolecular organic framework (SOF) was designed using CB[8] as the host and a novel bent-shaped cyanostilbene guest. The host-guest complex successfully formed a macrocyclic hexamer and exhibited significantly enhanced fluorescence (phi(F)=68%) compared to the non-assembled monomer (phi(F)=2%). Unlike other SOFs, this 0D SOF could be uniformly dispersed in water without bundling phenomenon.

Summary: Achieving precise control over topologically intricate molecular architectures remains a challenge for chemists due to their inherent structural complexity. We have demonstrated a simple solvent-free strategy to selectively prepare two multi-component supramolecular crystalline systems based on the halogen bond, one with an unknot topology and the other with a Borromean-type entanglement. Real-time in situ monitoring of the solvent-free mechanochemical synthesis of these three-component halogen-bonded ionic co-crystals revealed that the choice of milling conditions leads to a switch in the supramolecular reaction trajectory, resulting in the selective formation of an open halogen-bonded network or a halogen-bonded Borromean-type assembly.

Summary: This article highlights the main advances in using one-dimensional coordination polymers for adsorption and separation purposes, focusing on larger guest molecules and charged dyes or ions. In most cases, the adsorption processes induce significant structural changes in the CPs framework, as shown by extensive X-ray characterization. The dynamic properties of these compounds in responding to external chemical stimuli are inherent in their structural features, composed of chain-like arrays held together by weak inter-chain interactions.

Summary: Novel metallorganic materials were obtained by combing isoquinoline-5-carboxylic acid with Cu(II) ions under different conditions, including two 2D coordination polymers, CP 1 and CP 2, which were characterized by SC-XRD. The ratio of solvents (EtOH:DMF) used in the synthesis had a significant effect on the formation of different species, which differed in coordination at the Cu(II) center due to the denticity of the carboxylate ligands. Two fully characterized 2D coordination polymers formed exclusively depending on the DMF:EtOH solvent mixture are among the novel materials formed by the combination of Cu(II) with the isoquinoline-5-carboxylate ligand described here.

Summary: The trapping of volatile unbranched C-6 hydrocarbons (hexane, 1-hexene, and 1-hexyne) in a 1D coordination polymer is reported. The guest inclusion was quantitatively studied by H-1-NMR analysis and thermogravimetric measurements, while synchrotron single-crystal diffraction data allowed a better understanding of their confinement into linear CP channels. Adsorption experiments on microcrystals of CP 1 showed a certain degree of selectivity for 1-hexyne, potentially due to its larger dipole moment.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
