Metallogel formation in aqueous DMSO by perfluoroalkyl decorated terpyridine ligands

Abstract

Terpyridine based ligands 1 and 2, decorated with a C₈F₁₇ perfluorinated tag, are able to form stable thermoreversible gels in the presence of several d-block metal chloride salts. The gel systems obtained have been characterized by NMR, X-ray diffraction, electron microscopies and T_gel experiments in order to gain insights into the observed different behaviour of the two similar ligands, also in terms of the effect of additional common anionic species.
