Applications of Supramolecular Chemistry

Applications

Purification

Separation

Catalysis

Gas storage

Drug delivery

Selectivity of MOFs

Organic spacer or metallic SBUs can be altered

  • Control pore environment
  • Control of interactions with absorbates
  • Enables utilization for particular application

Metal Organic Frameworks

Secondary building units

Primary building blocks of MOFs

  • Primary building units exhibit characteristics roles in construction of secondary building units
  • Self assembly in higher dimensions
  • Organic spacers
  • Resulting MOFs

MOFs can be obtained:

  • Rigid molecular building blocks
  • Reaction conditions
  • Structural integrity through synthesis
  • A class hybrid supramolecular crystalline materials that consist of coordination bonds between metal ions and organic linkers.

  • Their structure is characterised by:
  • High surface areas
  • Tunable pore size
  • Functionality

Objective

  • Increasing environmental awareness and commercial constraint
  • Green synthetic processes
  • Eliminate of toxic/ organic solvents
  • High Temperature Water
  • Affords new routes to scale-up of material incorporation Green Chemistry Principles

Solvothermal reactions

Green chemistry challenge

Synthesis

  • Carried out in closed vessels
  • Autogenous pressure above the boiling point of solvent
  • High boling point solvents are most commonly used
  • Dimethyl formamide
  • Diethyl formamide
  • Acetone
  • Ethanol
  • Methanol
  • N,N- Dimethyl formamide
  • Toxic mutagen
  • Environmentally hazardous
  • Acute exposure causes liver damage in human and animals
  • Most syntheses are in liquid phase
  • Metal salt and ligand solutions
  • Solvent
  • Solid salt and ligand
