In recent years, luminescent materials with stimuli-responsive properties have attracted extensive attention. In this article, the gelation induced emission enhancement (GIEE) property of an 1,3,4-oxadiazole derivative (4-POXD-B8) was studied. The formation of the J-aggregate was viewed as the reason for this GIEE property, which was proved by UV-vis spectra. 4-POXD-B8 was found to exhibit a triple-channel (color, fluorescence and state change) response to trifluoroacetic acid (TFA). It was speculated that the reason for the acid responsiveness of 4-POXD-B8 was that the molecule was protonated after the addition of TFA, which can be confirmed by 1 H NMR and UV-vis spectra. In addition, the encryption-decryption process of information under visible and UV light was realized by using 4-POXD-B8 and TFA/triethylamine (TEA), which may provide some reference for future information storage.
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.
