Abstract

The emergence of aggregation-induced emission (AIE) in non-conjugated molecules challenges conventional paradigms in luminescent material design. Herein, we report the AIE activity of sucrose, a ubiquitous disaccharide devoid of traditional chromophores. While intrinsically non-emissive in dilute solution, sucrose exhibits robust luminescence upon aggregation, demonstrating a distinct AIE phenomenon. Furthermore, we exploit this property to develop a highly sensitive and selective fluorescence-quenching assay for ferric ions (Fe3+), achieving rapid and accurate detection. This discovery not only advances the fundamental understanding of AIE mechanisms but also highlights the potential of biocompatible saccharides for innovative sensing and optoelectronic applications.

蔗糖中的聚集诱导发光(AIE):揭示一种用于传感应用的新型发光现象
非共轭分子中聚集诱导发射(AIE)的出现挑战了传统的发光材料设计范式。在此,我们报告了蔗糖的AIE活性,蔗糖是一种普遍存在的双糖,缺乏传统的发色团。虽然在稀溶液中本质上不发光,但蔗糖在聚集时表现出强大的发光,表现出明显的AIE现象。此外,我们利用这一特性开发了一种高灵敏度和选择性荧光猝灭法,用于铁离子(Fe3+)的检测,实现了快速准确的检测。这一发现不仅促进了对AIE机制的基本理解,而且突出了生物相容性糖在创新传感和光电子应用方面的潜力。

期刊介绍: Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
