摘要

通过 Knoevenagel 缩合法，制备出了一种亚氨基香豆素和四苯基乙烯化合物，该化合物在 THF 中显示出聚集诱导发射（AIE）和显著的斯托克斯位移（Δλ = 135 nm）。TPICBT 还可用作近红外荧光探针，用于 F- 和 H2S 的裸色鉴定。它具有较大的红移（˃ 90 nm）、良好的选择性和抗干扰性。使用该探针可实现试纸检测和细胞成像。此外，该探针还可以在没有实验室仪器的情况下方便地检测食品腐败过程中产生的 H2S。

Novel Iminocoumarin-substituted Tetraphenylethylene-based Near-infrared Fluorescent Probe for Ratiometric Detection of F^- and H₂S.

An iminocoumarin and tetraphenylethylene compound that exhibits aggregation-induced emission (AIE) and a significant Stokes shift (Δλ = 135 nm) in THF was created via the Knoevenagel condensation method. TPICBT could also be used as a ratiometric near-infrared fluorescent probe for the naked color identification of F^- and H₂S. It showed a large red shift (˃ 90 nm), good selectivity, and anti-interference. Test strip detection and cell imaging had both been accomplished using the probe. In addition, the probe could conveniently detect H₂S produced during food spoilage without laboratory instruments.

期刊介绍： Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
