Enhanced luminescence sensing of pymetrozine pesticide in Cow milk using a Cd(ii) coordination network with sensitivity up to 0.448 ppm

A new coordination polymer, CP-1, synthesized with CdI 2 , BTC, and 3,4-dihydroxybenzoic acid, exhibits strong luminescence for pymetrozine detection with high quenching efficiency and photocatalytic activity, showing potential for food safety applications.
