One type for detecting explosive RDX base dihydro pyridine structure of the amide-based method for preparing the compounds

The invention relates to a preparation method of compounds used for detecting explosive RDX (Research Department eXplosive) and based on an acylamino dihydropyridine structure. The preparation method comprises the following steps: with Ce in a rare earth metal salt or Zn in a transition metal salt as a node and L as ligands, reacting to prepare compounds based on the acylamino dihydropyridine structure, wherein the synthesis route is Ce+L->Ce-L or Zn+L->Zn-L, the ligands L are respectively selected from H6ZPS and H6ZPT, the rare earth metal salt is cerium nitrate, and the transition metal salt is zinc nitrate; enabling the cerium nitrate and the zinc nitrate to respectively react with the ligands H6ZPS and H6ZPT to prepare the compounds Ce-ZPS and Zn-ZPT based on the acylamino dihydropyridine structure. The compounds based on the acylamino dihydropyridine structure, which are prepared by using the preparation method, are low in cost of raw materials, high in yield, stable in chemical property and easy to be put into practical application. When the detection limit reaches ppb level, the trace non-volatile non-aromatic RDX explosive which is difficult to detect by adopting conventional detection measures can be detected.

Fluorescent detection of RDX within DHPA-containing metal-organic polyhedra

By incorporating the dihydropyridine amido (DHPA) group into the rationally designed ligand systems, metal-organic molecular polyhedra were obtained via self-assembly for the luminescent sensing of highly explosive RDX with a limit of detection lower than 1 ppb in solution.
