Layered-Columnar Cathode Materials for Sodium-Ion Batteries

“…The structure of NaFe[O 3 PCH(OH)CO 2 ] 21 formed by the phosphoryl organic and Fe 2+ ions is shown in 1b, the calculated XRD diffraction peaks of the purple line are highly consistent with the reported PXRD diffraction peaks of the black line 21,23 . The calculated three strongest diffraction peaks at 19.95°, 30.42° and 31.97° correspond to the crystal planes (021), (222), and (213), respectively, while the experimental PXRD showed these peaks shifted to 19.98°, 30.19°, and 31.62°.…”

New 3D metal phosphonates with bright tunable luminescence for the reversible sensing of nitrobenzene

“…The peak band of solid 1-300 shows a 86 nm bathochromic-shift compared to that of as-prepaed 1, which maybe due to slightly irreversible changes of H 2 L 42 anion after heating treatment at 300 uC under an air atmosphere. 13 This indicates that luminescent colors of solid 1 can be irreversibly transformed from purple into blue-green by simple heat-treatment at 300 uC under an air atmosphere.…”

Synthesis, Structures and Recognition Properties of Two Cadmium(II) Phosphonates for Highly Selective Sensing of Cr2O72− and CrO42− Anions

“…Compared to the free ligand, compound 1 gave a fluorescent emission at λ max =420 nm under the same experimental conditions. It demonstrated that the emission spectra of compound 1 was attributed to the ligand–centered π–π* transition because their fluorescent emission bands were very similar to that of the free ligand . While the compound 2 displayed a fluorescent emission band at λ max =420 nm upon excitation at 325 nm.…”
