Simple and Efficient Synthesis and Surfactant Properties of N-Alkyl-3-Boronopyridinium Acid Triflates

In this paper, we describe a simple and efficient procedure of original N -alkyl-3-boronopyridinium triflates synthesis and report on the surface properties of these surfactants. Key micellar parameters were obtained, the critical micelle concentrations (CMC values) were determined and compared to conventional ionic surfactants as well as the surface activity of these surfactants ( pC 20 value and the surface tension at the CMC). These new boronic functionalized surfactants exhibit a stunning efficiency in their tendency to self-assemble and are significantly more surface active that their conventional analogues. This new family of surfactants represents a new direction in both functionality and performance, and may open perspectives in chemical synthesis and applications.
