Gelation-induced enhanced emission active stimuli-responsive low-molecular-weight organogelator: dual-channel recognition of cyanide from water and food samples with superhydrophobic surface formation

Abstract: A pyrene appended low-molecular-weight organogelator (LMWG) [2-(4-nitrophenyl)-3-(pyren-1-yl)acrylonitrile] (CN1) is presented which exhibits mechano-thermo responsive gelation, superhydrophobic surface formation and naked eye colorimetric and fluorogenic dual-channel cyanide sensing from different real...

“…11,12 Organogels form hierarchical architectures by selfassembly 13,14 through H-bonding, π-π stacking, van der Waals and electrostatic interactions 15 and metal ion coordination 16 with a gelator that exhibits an AIE property, which is often termed gelation induced emission enhancement (GIEE). [17][18][19][20] The three-dimensional porous network structure of a gel with a high surface-to-volume ratio enhances the adsorption, accumulation and diffusion of gaseous molecules, which enhance the sensitivity of the response. [21][22][23] Various organogels have been used to detect volatile acids, amines and explosives in their gel as well as xerogel states.…”
