“…39,40,41,42,43,44 Many of these metallogels have been used as matrices for the in situ formation of metal nanoparticles, mainly silver 45,46,47,48,49 and gold nanoparticles. 50,51,52,53,54,55,56,57,58,59 In this study, both C 12 -Cyc and click-C 12 -Cyc yielded precipitates in the absence of metal ions in polar aprotic solvents such DMSO. However, stable opaque metallogels were obtained in these solvents via a heating-cooling cycle upon incorporation of some metals.…”
