摘要

开发方便、快速的荧光传感器用于抗生素检测是公共卫生的迫切需要。结果合成了四种具有双态发射体（DSEs）的新型金属有机骨架，命名为ust -670 ~ 673。ust -670 ~ 673具有良好的结构稳定性和发光性，作为四环素类抗生素的荧光传感器，荧光颜色从蓝色到黄绿色不等。开发了便携式视觉检测棉签和可写mof膜，用于快速、简便地检测实际食品（如牛奶、牛肉）中的四环素，并进行简单的信息加密。该方法的回收率（98.1 ~ 100.3%）与HPLC法相当，相对标准偏差（RSD）小于1.42%。本工作突出了mof在食品检测和信息加密方面的应用前景，为后续的实际应用提供了实验基础。

Flexible metal-organic frameworks with dual-state emitters (DSEs) Photoluminescence for portable detection and information encryption

Background

Developing convenient, rapid fluorescent sensors for antibiotic detection is imperative for public health.

Results

In this article, four new metal-organic frameworks with dual-state emitters (DSEs) have been synthesized named as CUST-670∼673. CUST-670∼673 exhibit good structural stability and luminescence, serving as fluorescence sensors for tetracycline antibiotics with fluorescence color from blue to yellow-green. Portable visual detection cotton swabs and writable MOFs membranes were developed for rapid, easy detection of tetracyclines in real foods (e.g., milk, beef) and simple information encryption. The recovery rate of this method (98.1–100.3 %) is comparable to that of HPLC, with a relative standard deviation (RSD) below 1.42 %.

Significance

This work highlights MOFs' promising applications in food detection and information encryption, providing an experimental basis for subsequent practical use.
