Metal-Organic Frameworks via Emissive Metal-Carboxylate Zwitterion Intermediates. | LitMetric

AI Article Synopsis

  • Pyridinemethanol-carboxylate esters create octahedral complexes with Zn(NO ) in aqueous DMF, which can hydrolyze when heated.
  • The hydrolysis process results in the formation of metal-carboxylate zwitterions, with deprotonation of the hydroxy group occurring in situ.
  • This controlled, stepwise synthesis allows for the creation of stable, neutral metal-organic frameworks (MOFs) by manipulating temperature and taking advantage of the varying reactivity of the functional groups.

Article Abstract

Pyridinemethanol-carboxylate esters form octahedral complexes with Zn(NO ) in aqueous DMF that subsequently undergo hydrolysis at elevated temperatures to form metal-carboxylate zwitterions. In situ deprotonation of the hydroxy group leads to thermally robust, neutral MOFs. This stepwise synthesis can be controlled by temperature and is made possible by the subtle difference in reactivity of the functional groups.
