Structure and luminescence of a one-dimensional uranium coordination polymer assembled through benzophenone-4,4′-dicarboxylate

• A 1D uranium coordination polymer was hydrothermally synthesized.
• This compound displays vibrant green emission upon UV excitation.
• Emission, excitation, and reflectance spectra are discussed.
• This compound is thermally stable up to 245 °C.

Uranyl nitrate reacts under hydrothermal conditions with benzophenone-4,4′-dicarboxylic acid to produce a one-dimensional coordination polymer constructed through a double-chain motif. Upon excitation of the organic component in the near-UV, sensitized uranyl emission is observed. Thermogravimetric analysis demonstrates that this material is stable until 245 °C.

The reaction of uranyl nitrate with a benzophenonedicarboxylate under hydrothermal conditions produces a 1D coordination polymer that displays typical uranyl emission upon UV excitation of the organic component of the compound.Figure optionsDownload as PowerPoint slide
