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
