A supramolecular polymer network constructed by pillar[5]arene-based host-guest interactions and its application in nitro explosive detection

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 x 10(-7) M and 4.40 x 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.
