Abstract
Three novel coumarin-based arylpyrazolines were successfully designed and synthesized. Among them, probe B3 demonstrated excellent detection capabilities for Cu2+. According to the fluorescence titration and Job's plot, B3 could form a complex with Cu2+ in a 2∶1 ratio, the detection limit was 1.71 × 10 - 8 mol·L- 1, and the combining constant was 2.30 × 105 L·mol- 1. B3 exhibited outstanding selectivity, high sensitivity, and strong anti-interference ability towards Cu2+. Meanwhile, this series of compounds exhibited remarkable optical properties and a large Stokes shift. Compound B3 exhibited aggregation-induced emission enhancement (AIEE) property in tetrahydrofuran/cyclohexane (THF/CYH) system. Interestingly, B1-B3 displayed reversible mechanofluorochromic (MFC) behavior under external force.
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.
