Spectroscopic Properties of New Cerium Metal–Organic Framework Based on Phosphonate Ligands with Vinyl Functional Group

GRAPHICAL ABSTRACT

Abstract

Phosphonate framework structures are now known with a variety of transition metals, p-block elements as well as lanthanides.^1–3 The self-assembly of such phosphonate metal organic frameworks depends on numerous synthetic parameters related to the reaction conditions: temperature, time, reactant molar ratio, pH, pressure, and structural factors, such as: nature of incorporated metal, geometry of the phosphonic acid, protonation degree, presence of other coordinating moieties on the phosphonate backbone.^4,5 Cerium vinylphosphonate was obtained in our laboratories by the reaction of Ce(NO₃)₃^.6H₂O, vinyl phosphonic acid in 2:3 ratio under hydrothermal conditions.
