Summary: In this study, a water-soluble fluorescent probe TPE-M was designed and synthesized for the detection of hypochlorous acid. The results showed that TPE-M exhibited excellent water solubility and could solely recognize hypochlorous acid. The detection limit of the fluorescent probe for hypochlorous acid was calculated to be 0.25 μM.

Summary: We synthesized cationic regioisomeric acrylonitriles with aggregation-induced emission (AIE) properties by conjugating tetraphenylethylene at different ortho/meta/para positions. The regioisomerism significantly influenced their photophysical characteristics and solid-state intermolecular interactions. These AIE luminogens showed enhanced fluorescence behavior in the solid state compared to solution, with o-TPE-ANPy(+) and m-TPE-ANPy(+) emitting yellow light and p-TPE-ANPy(+) emitting red-shifted light. Additionally, m-TPE-ANPy(+) and p-TPE-ANPy(+) displayed higher fluorescence enhancements with increasing viscosity than o-TPE-ANPy(+). Lastly, o-TPE-ANPy(+) was successfully applied for reversible mechanochromic performance and wash-free imaging of mitochondria. These findings contribute to a better understanding of the structure-property relationships in fluorescent regioisomers.

Summary: The supramolecular assembly of DNA conjugates with tetraphenylethylene (TPE) sticky ends into vesicular structures is studied in this research. The aggregation-induced emission (AIE) active TPE units are used to monitor the assembly process using fluorescence spectroscopy. The number of TPE modifications on the conjugates' overhangs influences the supramolecular assembly behavior, with a minimum of two TPE residues required for a well-defined assembly process. The designed DNA-based nanostructures offer customized functionalization for applications in DNA nanotechnology.
