Questions and Answers

What is the most basic functional group among the nitrogen-based functionalities found in the mentioned MOFs?

  • Nitrogen atoms in organic ligand
  • Azo group with two nitrogen atoms
  • NH2-group of 2-aminoterephtalic acid (correct)
  • Nitrogen atoms coordinated to copper ion

Why does Cu-URJC-1 not have as high basicity as Cu-URJC-8?

  • Due to the presence of copper ions
  • Because of the presence of azo group
  • Due to the inductive effect (correct)
  • Because of the lack of nitrogen atoms

Why is the azo group in JUC-62 less available to interact with CO2 molecules?

  • Due to the lack of copper ions
  • Because of the inductive effect
  • Due to the presence of NH2-group
  • Because of the mutual electronegative effect (correct)
