Construction of porous ionic liquids based on coordination cages

Project description

A new recipe combines just the right ingredients, leading to the first permanently porous liquid

Ionic liquids got their start more than a hundred years ago in a publication describing the special physical properties of ethylammonium nitrate. Only in the last couple of decades have they gained significant attention for their unique and tuneable properties compared to conventional molecular compounds and their extensive use as green solvents and in green chemistry. The solidification of fluidic ionic liquids into porous ionic materials creates porous ionic liquids (PILs) combining the uniqueness of ionic liquids with the processability and stability of polymers and porous materials. The EU-funded PIL project is pioneering the first-ever version of PILs to house gaseous and non-gaseous molecular guests in a variety of applications.

Objective

The key objective of this fellowship proposal is to develop the first ever porous ionic liquid (PIL) at the molecular level and to explore their properties as Type I permanently porous liquids. Transition-metal coordination cages, in which organic ligands coordinate to metal cations to form a molecular capsule, will be used as scaffolds for permanently PIL. Such coordination cages have been developed by the Nitschke group. In the target PIL, the cations will be coordination cages and will thus contain an empty cavity. The strategy employed to synthesize permanently PIL will be functionalizing a task-specific coordination cages with imidazole cations together with the selection of proper anions in order to liquefy coordination cages at room temperature . The researcher will also explore the guest encapsulation properties of these new liquid capsules by monitoring guest uptake in neat permanently porous liquid.
