Abstract

A novel class of anion-exchange polymers based on cation cross-linked ionic liquids (CCLIL) with anion-exchange capabilities has been reported. The development of sorbents for these anions is very important for their effective removal from contaminated sites. Anion-exchangeable CCLIL were prepared by introducing 0.5 g of a particular TSIL into an alumina crucible placed within a quartz tube furnace. Energy-dispersive X-ray analysis (EDAX) results for CCLILs derived at 400 °C reveal a significant retention of anions in the corresponding cross-linked polymers. The new method relies on the synergistic properties of negligible vapor pressure and incorporation of cross-linkable functional groups into our TSIL starting materials. The structural morphology such as porosity and surface area and adsorption capacity of these porous materials are highly dependent on the structural motif of the corresponding TSIL precursor.
