“…Picolinium salts have, in many cases, been used as intermediates for the preparation of donor-acceptor molecules for the construction of promising photo- and electro-active materials [ 29 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. In addition, their typical physicochemical features such as surface activity and micellization have been intensively studied in the line of their possible application [ 39 , 40 , 41 , 42 , 43 , 44 ]. For instance, N -( n -hexadecyl)- and N -( n -heptadecyl)-3-methylpyridinium bromide or 1-methyl-3-octylpyridinium alkyl sulfate were found to be effective for micelle-based drug delivery to improve drug solubility and the bioavailability of anionic drugs and metal complexes [ 28 , 43 ].…”

Nosocomial infections, which greatly increase morbidity among hospitalized patients, together with growing antibiotic resistance still encourage many researchers to search for novel antimicrobial compounds. Picolinium salts with different lengths of alkyl chains (C12, C14, C16) were prepared by Menshutkin-like reaction and evaluated with respect to their biological activity, i.e., lipophilicity and critical micellar concentration. Picolinium salts with C14 and C16 side chains achieved similar or even better results when in terms of antimicrobial efficacy than benzalkoniums; notably, their fungicidal efficiency was substantially more potent. The position of the methyl substituent on the aromatic ring does not seem to affect antimicrobial activity, in contrast to the effect of length of the N-alkyl chain. Concurrently, picolinium salts exhibited satisfactory low cytotoxicity against mammalian cells, i.e., lower than that of benzalkonium compounds, which are considered as safe.

“…The surface activity of ILSs solutions can be characterized by the adsorption efficiency (pC 20 ) and the surface pressure (p CMC ). The adsorption efficiency can be calculated by the following equation: 18,27,28 The maximum surface excess (G MAX ) and the minimum surface cross sectional area (A MIN ) of the ILSs are calculated by the following eqn ( 5) and ( 6), respectively. 18,27,28…”

In our previous work N-phthalimidomethyl methacrylate (NPMMA) monomer was prepared through the reaction of Nhydroxymethyl phthalimide with methacrylic acid in the presence of N, N-dicyclohexylcarbodiimide (DCCI) as a condensing agent. Then a new series of copolymers containing imidazole have been synthesized through the reaction of NPMMA monomer with 1-vinylimidazole (VIM) in the presence of benzoyl peroxide as initiator. The copolymer composition was determined by 1 H NMR spectroscopy and the values of monomer reactivity ratio (r1= 0.756, r2= 1.033, and r1r2= 0.781) were calculated through Fineman Ross and Kelen-Tüdös methods. Conversion of copolymers to surfactants was achieved through quaternization of the imidazole nitrogen with dimethyl sulphate. The chemical structure of the produced monomer, copolymers, co-polymeric surfactants was confirmed by spectroscopic tools. The surface properties included surface tension, foaming power, emulsion stability, critical micelle concentration (CMC) have been measured in aqueous medium by traditional procedures. Also the different air/ water interface parameters including effectiveness (πcmc), efficiency (Pc20), maximum surface excess (Γmax) and minimum surface area (Amin) were also recorded. Moreover, the biodegradability for these cationic surfactants has been investigated and their D % was ranged from 67 to 100 %.
