Abstract

Functionalized guanidinium ionic liquids as a new class of versatile organic materials have been developed. Guanidinium salts containing olefinic functionalities have been prepared and completely characterized. In order to illustrate the versatility of olefinic units, they were brominated and some bromine-containing ionic liquids have been obtained. Relevant physico-chemical properties of the new synthesized salts were evaluated including their melting points, glass transition temperatures, miscibilities, densities, surface tensions and contact angles with glass and Teflon surfaces. Additionally toxicity studies were performed using the human colon carcinoma CaCo-2 cell line. Several new functionalized guanidinium based ILs showed high densities, low contact angles with Teflon, low surface tensions as well as a non-toxic behaviour.
