Cationic gemini surfactants are a special class of second-generation smart surfactants. Since Menger first named them, gemini surfactants have drawn a wide and immense attraction from scientists throughout the whole world. These dimeric surfactants possess two or more hydrophilic with two or more hydrophobic head groups, chemically bonded with a linker, called the spacer group. These kinds of surfactants are used mainly in homogeneous catalytic reactions, as well as for solubilisation, emulsification, and many more technical applications. They are used in industries for electro-decoating, stabilization of adhesive polymer latex, antifriction agents, mining, paper manufacturing, preparation of surfactants including softeners, cosmetics, and most importantly, recent advancement in drug designing, synthesis, and application in medicine. The aim of this paper is to bring attention to the high performance second generation interfactants, with a focus on their synthesis, structure, types, and greener industrial application with high possibility of future prospect.

“…In general, many conventional single-chain surfactants were employed as monomers for the formation of micellar aggregates. Besides our study, only a few reports [30][31][32][33] have studied the application of Gemini surfactants with high surface activity in the field of esterolysis [8,9,34].…”

Cl under a comparable condition, which confirmed that an open active centre is essential for modulating the activities of the two enzyme mimics. Moreover, under the conditions employed, hydrolytic rates of PNPP induced by these Mn(III) complexes were faster in Gemini 16-2-16 micelles than that in the micellar solution of cetyltrimethylammonium bromide (CTAB), a conventional analogue of Gemini 16-2-16.

“…In the past two decades, many studies [3][4][5][6][7][8][9][10][11] have focused on the synthesis of artificial enzymes with various structures, especially with respect to access to the active site and hydrophobic microenvironment. As expected, a relatively open active site is important for the association between guest molecule and enzyme [12].…”

Two mono-Schiff base Mn(III) complexes were used to catalyze the hydrolysis of p-nitrophenyl picolinate (PNPP) in micellar solutions of n-lauroylsarcosine sodium (LSS) and polyoxyethylene(23) lauryl ether (Brij35). The results show that both catalysts enhance the hydrolysis of PNPP by over two orders of magnitude relative to the spontaneous rate at 25°C. Moreover, Mn(III)-promoted hydrolysis of PNPP was faster in LSS micellar solution than in both Brij35 micellar solution and pure buffer. Experimental sectionAll reagents, unless otherwise indicated, were of analytical grade and used without further purification. Ultrapure water used in the preparation of all the solutions was obtained from a Water Purification System (Nex Power 1000, Human Corporation, Korea) to achieve a resistivity of at least 16 MX cm -1 . The resulting pH of reaction solution was Electronic supplementary material The online version of this article (
