Abstract

Abstract : The article describes the role of a novel amide based supergelator in gelating a wide range of copper salts. The metallogel was highly stable to heat, stress and mineral acids showing an unprecedented colorimetric gel-to gel sensing of amine vapours. Abstract : In this manuscript we have described the role of a novel pyridine–pyrazole based bis amide molecule namely N 1, N 3 -bis[5-(pyridin-2-yl)-1 H -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.
