| titleOfInvention | A kind of PADAP derivative, its preparation method and application |
| abstract | The present invention provides a PADAP derivative, as shown in formula (I); wherein, X is halogen, and R 1 and R 2 are each independently selected from C1-C20 alkyl groups. Compared with the prior art, the present invention simultaneously introduces electron-withdrawing groups and large conjugated groups into PADAP to form PADAP derivatives, which show significant color changes before and after binding uranyl ions, and have higher selectivity, resistance Anion-cation competition, recyclability, and sensitivity make it a good ligand for the recognition of trace uranyl ions in the environment. |
