“…Meanwhile, the coordinated U−O bond distances range from 2.275(4) to 2.493(4) Å, which is in close agreement with the U−O bond distances reported in the literature. 23,24 As observed from Figure 2d, two uranyl ions are connected by two parallel deprotonated CMNDI ligands to form a discrete uranyl dimer structure. In each CMNDI ligand, the two carboxyl groups are oriented in a trans position relative to the NDI plane, resulting in an overall centrosymmetric chairlike structure.…”

It can provide ideas for the use of uranium elements in the treatment of spent fuel from nuclear wastewater to explore the application potential of uranium element. Thus, it is necessary to research the structure and properties of a novel uranyl coordination polymer (CP) for uranium recovery and reuse. Herein, we designed and prepared a new uranyl CP U-CMNDI based on UO 2 2+ and H 2 CMNDI (H 2 CMNDI = N, N′-bis-(carboxymethyl)-1,4,5,8-naphthalenediimide). Structural analysis shows that two uranyl ions are connected by two parallel deprotonated CMNDI ligands to form a discrete uranyl dimer structure. U-CMNDI can act as a potential stimulus-responsive halide ion sensor by a fluorescence "turn on" response in water. The limit of detection for fluoride (F − ), bromide (Br − ), iodide (I − ), and chloride (Cl − ) is 5.00, 5.32, 5.49, and 5.73 μM, respectively. The fluorescence "turn on" behavior is based on the photoinduced electron transfer (PET) mechanism between halide ions and electron-deficient NDI cores. In addition, U-CMNDI demonstrates a color response to ultraviolet light, exhibiting reversible photochromic behavior with a notable color change. The color change mechanism can contribute to the PET process and the radical process.
