Summary: Three novel bis(tetraphenylethene) (BTPE) derivatives were efficiently synthesized, all displaying aggregation-induced emission characteristics. Linking two tetraphenylethylenes via a sulfur atom with different oxidation states offered compounds showing reversible mechanofluorochromic behavior. Notably, sulfone-based BTPE 3 exhibited polymorphism and three observable morphologies could be interconverted.

Summary: The spread of antibiotic resistant bacteria from wastewater to the environment poses serious threats to human health. A potential solution is to use photosensitizers with broad-spectrum antibacterial activity for photo-oxidation in wastewater treatment. In this study, an aggregation-induced emission photosensitizer, TBTPy, was successfully designed and developed. TBTPy can efficiently generate singlet oxygen under white-light irradiation, leading to rapid and effective photo-oxidative killing of bacteria and fungi.

Summary: In this study, a bifunctional electrocatalyst with abundant heterointerfaces and sulfur vacancies on graphene (Cu1Ni2-S/G) was prepared for oxygen reduction and alcohols oxidation reactions (ORR, AOR). The Cu1Ni2-S/G catalyst showed significantly enhanced ORR activity with long term stability and achieved a high Faradaic efficiency for ethyl acetate production during AOR. The study highlights the synergistic effects of interfacial coupling and vacancies engineering in tailoring catalytic activity and opens up new avenues for self-driven biomass electrocatalysis systems.

Summary: Five square-planar [Pt(C^N*N 'C ')] complexes with novel nonsymmetric tetradentate ligands were synthesized and characterized, showing substantial changes in photophysical properties and intermolecular interaction mode in solution and in solid state by varying the structure of the metalating aromatic systems. Some of these complexes exhibited aggregation-induced emission phenomenon in water and mechanochromism in the solid state, which were attributed to the excited states of Pt-Pt bonded aggregates of the complexes.

Summary: Photodriven self-assembly is a crucial strategy to regulate the molecular orderliness and structure. While traditional photochemical self-assembly has disadvantages, physical processes based on photoexcitation can fully utilize photons to avoid drawbacks. These processes drive molecular movement and aggregation, promoting the assembly of materials. The exploration of photoexcitation-induced assembly can lead to the development of unprecedented optoelectronic materials.

Summary: Selective and sensitive detection of inorganic pyrophosphate (PPi) was achieved using a ratiometric fluorescent probe based on a porphyrin-based metal-organic framework (PCN-224) decorated with sulfur nanodots (S-dots). The red-fluorescence of PCN-224 was enhanced by S-dots, which also provided active sites for the detection of Cu2+ and PPi. Cu2+ selectively quenched the red-fluorescence, while PPi competed with Cu2+ and resulted in fluorescence recovery. The blue-fluorescence from S-dots served as an effective reference for correction in complex environments.

Summary: In this study, a promising and cooperative strategy was proposed to prepare smart luminescent hydrogels. By constructing interwoven double networks through a noncovalent hydrogen bonding model between polyethylene glycol (PEG) and polyurethane (PU), the hydrogels exhibited improved mechanical properties. Lanthanide(III)-based complexes (LnCs) and sulfur quantum dots (S-QDs) were used as emitting centers, allowing for color modulation of the hydrogels by varying the UV irradiation wavelength. The hydrogels also showed good mechanical performance and self-healing capability, and could selectively detect Cu2+ as a ratiometric luminescence probe.

Summary: In this study, a d-penicillamine@Ag/Cu nanocluster (DPA@Ag/Cu NCs)-based fluorescence assay was developed to screen organophosphate pesticides (OOPs). The fluorescence intensity of DPA@Ag/Cu NCs was reduced when thiocholine produced by acetylcholinesterase (AChE) enzymatic splitting of acetylthiocholine chloride reduces the transmission of electrons. OOPs act as AChE inhibitors and retain high fluorescence while SOPs show low fluorescence intensity due to weaker toxicity to AChE. DPA@Ag/Cu NCs can be used as a fluorescent nanoneuron to construct Boolean logic tree and complex logic circuit for molecular computing.

Summary: Co-doping of double perovskites with Bi3+ and Te4+ ions improves their stability and enhances photoluminescence quantum yield. The introduction of Te4+ ions promotes the radiative recombination of self-trapped excitons in Cs2AgInCl6 nanocrystals. Excess use of the TeO2 precursor leads to the generation of residual TeO2, Te2O3Cl2, R2TeO, which improves coordination with surface oleic acid ligands. The co-doped Cs2AgInCl6 nanocrystals with 1% Bi and 8% Te exhibit a high photoluminescence quantum yield of 34% and excellent stability, retaining over 70% of their original emission intensity after storage for more than 1 month.
