Abstract

In this manuscript we have described the role of a novel pyridine–pyrazole based bis amide molecule namely N1,N3-bis[5-(pyridin-2-yl)-1H-pyrazole-3-yl]-terephthalamide (BPPTP) which acts as a supergelator in forming very strong gels with copper triflate at a concentration as low as 0.3 wt%. The gel was found to be highly stable towards heat, mineral acids and mechanical stress thus showing self-sustainability. The xerogel showed not only high N2 gas sorption properties seldom reported for metallogels, but also good toxic dye sorption and rare amine sensing properties in gel state.
