Abstract

The development of reliable methods for the rapid and selective detection of nitro-explosive were vital concern for national security due to the increasing use of explosive materials in terrorism, military operation safety, industrial and environmental safety control. Here a novel cross-linked supramolecular polymer network (SPN5) was efficiently constructed by pillar[5]arene-based host–guest interactions, which can be used for nitro explosives o-DNB and p-DNB detection. The limits of detection (LODs) of SPN5 for o-DNB and p-DNB were determined as 7.90 × 10⁻⁷ M and 4.40 × 10⁻⁷ M, respectively. Moreover, the detection of o-DNB and p-DNB was also realized in a thin film consisting of the SPN5. This work provided a novel strategy for efficient detection of explosives.

柱[5]芳烃主客相互作用构建的超分子聚合物网络及其在硝基炸药探测中的应用

由于爆炸性材料在恐怖主义、军事行动安全、工业和环境安全控制中的使用越来越多，开发可靠的方法来快速和选择性地检测硝基炸药是国家安全的重要关注点。本文利用柱[5]芳烃主客相互作用构建了一种新型交联超分子聚合物网络(SPN5)，可用于硝基炸药o-DNB和p-DNB的检测。SPN5对o-DNB和p-DNB的检出限(lod)分别为7.90 × 10−7 M和4.40 × 10−7 M。此外，在由SPN5组成的薄膜中也实现了o-DNB和p-DNB的检测。这项工作为有效探测爆炸物提供了一种新的策略。

期刊介绍： The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
