Crystal Structure,Characterization and Calorimetric in Situ Synthesis of Microporous Pr-MOF Based on Triangular Tricarboxylic Acid Ligand
One new microporous Pr(Ⅲ)-MOF,named as[Pr(TATB)(H2O)](1),has been synthe-sized from 4,4',4"-triazine-2,4,6-triyl-tribenzoate(H3TATB)with praseodymium salt under hydrother-mal conditions.Structural analysis shows the complex exhibits a three-dimensional framework featur-ing the co-edged binuclear metal units.The CO2/N2 adsorption experiments of 1 demonstrate the higher CO2 uptake and the microporous structure.The luminescence spectra of 1 have been studied in the solid state and display characteristic transitions of the Pr3+ion in the visible light range.The synthesis pro-cess of 1 could be divided into three stages when simulated by microcalorimetry in situ at 413.15 K,and the reaction rate constant of crystallizing is gained with the value of k=2.91×10-10.
