Abstract

In this research, we synthesized and constructed a novel gelator (named) combining quinoline and naphthalene that self-assembled in N, N-dimethylformamide (DMF) to form a stable supramolecular gel (named). Under UV light, gelexhibited extremely bright yellow fluorescence. The gelshowed excellent sensing performance for both Feand Cu, with a fluorescence 'turn-off' detection mechanism and the lowest detection limit of 7.58 × 10M and 1.51 × 10M, respectively. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectra, x-ray powder diffraction (XRD), rheological measurements, x-ray photoelectron spectroscopy (XPS), and fluorescence spectroscopy were used to characterize the gel. Theion-responsive membrane created is an excellent fluorescent writing material.

摘要

在本研究中，我们合成并构建了一种结合喹啉和萘的新型凝胶因子（命名为），其在N，N - 二甲基甲酰胺（DMF）中自组装形成稳定的超分子凝胶（命名为）。在紫外光下，凝胶呈现出极其明亮的黄色荧光。该凝胶对Fe和Cu均表现出优异的传感性能，具有荧光“猝灭”检测机制，最低检测限分别为7.58×10⁻⁸M和1.51×10⁻⁷M。利用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、傅里叶变换红外（FTIR）光谱、X射线粉末衍射（XRD）、流变学测量、X射线光电子能谱（XPS）和荧光光谱对凝胶进行了表征。所制备的离子响应膜是一种优异的荧光书写材料。
