Summary: In this study, a fluoran salicylaldehyde hydrazone metal complex (FSHMC) was modified with an aggregation-induced emission (AIE) moiety, tetraphenylethene (TPE), to create the compound 2-Zn. This compound exhibited reversible color and fluorescence changes upon UV light irradiation due to the unique emission properties of the AIE moiety. The fluorescence resonance energy transfer (FRET) process from the TPE moiety to the rhodamine B moiety allowed for different emission changes in THF solution and solid matrix under UV light irradiation.

Summary: Aggregation-induced emission (AIE) polymers have been extensively studied for their potential applications in developing new polymer nanoparticles or polymer dots (Pdots) with excellent fluorescence properties. We synthesized conjugated copolymers based on carbazole (Cz) and tetraphenylethene (TPE), a common AIEgen, and found that the presence of an ethynylene spacer between Cz and TPE units resulted in aggregation-caused quenching (ACQ) properties. The ethynylene spacer played a critical role in determining the fluorescent properties of the copolymers in solid states.

Summary: Combining AIE scaffolds with ACQ luminophores can eliminate the ACQ effect and give derived molecules new optical behavior. The manner in which the AIE scaffold connects with the ACQ luminophore determines the properties of the resulting molecules. Differences in the connection of pyrene with the ester group led to distinct fluorescence properties in molecules 1 and 2, with molecule 1 showing potential for optical recording applications.

Summary: Polyarylethenes are synthesized through electrophilic C-H vinylation reactions, resulting in hyperbranched polymers with size-dependent luminescence and unusual ratiometric aggregation-induced emission behavior. The vinylation reactions are mediated by acid-induced cleavage of a triazene function, and the methodology used is traceless, with no functional groups present in the products. Additionally, the synthetic methodology can be applied to graft hyperbranched poly(triphenylethene) to a functional aromatic compound, displaying a ratiometric luminescence response upon the addition of metal salts.

Summary: Monodisperse polymer hemispheres were fabricated by seed emulsion polymerization, and their morphology was studied using fluorescent microscopy and super-resolution imaging. The polymer colloids were found to consist of hydrophobic cores and hydrophilic surfaces, with a thin hydrophilic surface layer. During seed emulsion polymerization, microphase separation occurred inside each polymer colloid, causing an uneven distribution of the chemical composition. The final shape of the polymer colloids was determined by the postpolymerization washing process.

Summary: Metal chalcogenides are highly promising anodes for LIBs and SIBs due to their high capacities, thermal stabilities, and low price. However, their poor conductivity and large volume expansion hinder their commercial applications. Electrospun 1D carbon-source nanostructures can effectively address these issues. This comprehensive review focuses on the development of metal chalcogenide nanomaterials by electrospinning for LIBs and SIBs, and discusses the progress of metal oxides, metal sulfides, and metal selenides. The future outlook of electrospun metal chalcogenide materials and the potential for other energy-storage devices are also highlighted.

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.
