Diaminomalenonitrile decorated cholesterol-based supramolecular gelator: Aggregation, multiple analytes (hydrazine, Hg2+ and Cu2+) detection and dye adsorption

Abstract

Diaminomalenonitrile functional group containing low molecular weight gelator (LMWG) 1 has been designed and synthesized. The compound forms supramolecular gels from DMF-H2O and 1,2-dichlorobenzene. The morphology of the gels reveals the fibrous networks. The rheological study demonstrates that DMF-H2O gel is stable and robust than that of the gel obtained from 1,2-dichlorobenzene. This is attributed to the existence of strong intermolecular forces among the gelators in DMF-H2O. Analysis of tan δ values from frequency sweep (tan δ = G′′av/ G′av, ) indicates that the DMF-H2O gel exhibits higher mechanical strength (lower tan δ) than the 1,2-dichlorobenzene gel. The DMF-H2O gel has been explored in sensing and dye adsorption. The gel is established to be selective for visual recognition of hydrazine, Hg2+ and Cu2+ ions. Moreover, the gel exhibits excellent efficacy towards rapid and selective adsorption of cationic dyes from water in almost no time (˂ 1 min).
