Abstract

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.

1,3,4-恶二唑衍生物:凝胶诱导的发射增强和三通道酸响应性质。
近年来,具有刺激响应特性的发光材料引起了广泛的关注。本文研究了一种1,3,4-恶二唑衍生物(4-POXD-B8)的凝胶诱导发射增强(GIEE)性质。j聚集体的形成被认为是这种GIEE性质的原因,并通过紫外可见光谱证明了这一点。发现4-POXD-B8对三氟乙酸(TFA)表现出三通道(颜色、荧光和状态变化)反应。推测4-POXD-B8具有酸响应性的原因是在加入TFA后分子被质子化,这可以通过1h NMR和UV-vis光谱得到证实。此外,利用4-POXD-B8和TFA/三乙胺(TEA)实现了可见光和紫外光下信息的加解密过程,可为今后的信息存储提供一定的参考。

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.
