series of novel asymmetrical bis-surfactants (CnNCS, n = 10, 12, 14, 16), comprising a naphthalene group and a long chain hydrocarbon (as hydrophobic moieties), a quaternary ammonium group, one ether group and double amides (as hydrophilic moieties), and ethylidene as linkage groups, were designed, prepared, and characterized through proton and carbon nuclear magnetic resonance, Fourier-transform infrared
A series of novel haloglycolipids were synthesized based on Cu(I) catalyzed Huisgen's [3 + 2] cycloaddition reaction of diversely functionalized azides and alkynes, using a mixture of N-bromosuccinimide and Cu(I) halide as the halogensource. Since halogen atoms, like bromine and iodine, with a very high scattering power facilitate the solving of crystal structures, the title haloglycolipids could

A series of 1-(2-(alkylamino)-2-oxoethyl) pyridinium chloride surfactants was designed and synthesised by two steps. Four new compounds were obtained. The structures of all the synthesised compounds have been characterised by IR, 1H NMR and elemental analyses. Surface activity and antibacterial activity of 1-(2-(alkylamino)-2-oxoethyl) pyridinium chloride surfactants were investigated. The critical

The formation of ultra-thin 2D crystalline nano-sheets, -spindles and -ribbons by self-assembly of benzimidazolium-based single-tailed surface active ionic liquids (SAILs) is observed for the first time. The nature of formed bilayer architectures is governed by the functionalization of alkyl chains of SAILs via an amide or ester moiety.
