Article Abstract
A Schiff-based aggregation induced emission (AIE) fluorescent probe with excited intramolecular proton transfer (ESIPT) mechanism was synthesized by grafting 2-hydrazinobenzothiazole onto 2,6-diformyl-4-methylphenol. The probe recognizes Zn selectively and sensitively, accompanied by a significant fluorescence emission increasement change from light yellow-green to strong green. Additionally, a stabilization time of at least 30 min was kept in the recognition process. Besides, a linear relationship was observed between the concentration of Zn and the fluorescence intensity at 525 nm (0.05-10 µM). And thus, the probe can detect Zn quantitatively in aqueous solution with a low detection limit of 1.9 × 10 M. Based on the AIE property and the selective recognition of Zn, SCH was strategically loaded on the filter paper to develop a novel paper-based indicator for on-site and high-efficiency detection of Zn. The results showed that the paper-based indicator could be conveniently applied to the visual inspection of Zn as expected and SCH in the paper-based indicators fortunately exhibited a better stability. Furthermore, our comprehensive application evaluations have confirmed that SCH was capable of detecting Zn in real water samples and imaging Zn in living cells roundly.

A series of 2-substituted 4H-chromen-4-ones 3a-3h containing triphenylamine or N-phenylcarbazole on the benzene ring were synthesized for the first time via the Suzuki coupling reaction. The photophysical properties of the compounds and their relationship to the structure of the compounds were investigated by methods such as spectroscopic analysis, single-crystal analysis, and theoretical calculations. The systematic results indicate that compounds 3a-3h have intramolecular charge transfer (ICT), aggregation-induced emission (AIE), and dual-state emission (DSE) effects with a wide range of fluorescence emission wavelengths (421-618 nm), showing the potential to be developed into a full-color fluorophore.

Multimodal phototheranostics has been recognized as one of the most momentous advances in cancer treatment. Of particular interest is a single molecular species simultaneously featuring in multiple imaging and synergistic phototherapies; the development of such a molecular species is nevertheless a formidably challenging task. Herein, we innovatively designed and synthesized three aggregation-induced emission (AIE)-active molecules with emission in the second near-infrared (NIR-II) window, by employing 10-indeno[1,2-][1,2,5]thiadiazolo[3,4-]quinoxalin-10-one as the electron acceptor, 4-(-butyl)--(4-(-butyl)phenyl)--phenylaniline as the electron donor, and different π-bridge moieties.

A novel aggregation-induced emission (AIE) system with superior performance was successfully developed through local chemical modification from thiophene to thiophene sulfone. This approach, leveraging easily accessible tetraphenylthiophene precursors, dramatically enhances the photophysical properties in a simple oxidation step. Notably, the representative 2,3,4,5-tetraphenylthiophene sulfone (3c) demonstrates remarkable solid-state emission characteristics with a fluorescence quantum yield of 72% and an AIE factor of 240, substantially outperforming its thiophene analog.

Osteoarthritis (OA) is a common degenerative joint disease, and early diagnosis and effective treatment are essential for managing its progression. This study focuses on the development of a novel drug delivery system using aggregation-induced emission (AIE) probe for enhanced fluorescence imaging and targeted therapy in OA. TPE-S-BTD, an AIE probe, is synthesized and characterized for its photophysical properties, demonstrating significant aggregation-induced fluorescence enhancement.

Background: The development of specific fluorescent probes for cancer cell discrimination holds significant promise for advancing cancer diagnostics. Conventionally, these probes operate by translating differences in biomarkers or microenvironmental factors into variations in whole-cell fluorescence intensity. However, this dominant, intensity-based strategy is highly susceptible to extraneous fluctuations arising from probe concentration, illumination instability and complex intracellular environment.
