A synthetic route to sulfobetaine methacrylates with varying charge distance
Kratzer, Domenic, Barner, Leonie, Friedmann, Christian, Braese, Stefan, & Lahann, Joerg (2014) A synthetic route to sulfobetaine methacrylates with varying charge distance. European Journal of Organic Chemistry, 2014(36), pp. 8064-8071.
A general synthetic strategy is described that enables access to a library of new sulfobetaine methacrylates starting from commercially available precursors. The three-step procedure allows the distance between the quaternary amine and the sulfonate group (inner charge distance) to be varied by selecting the corresponding dibromoalkane in the first step. A key step is the final esterification, in which methacrylic acid acts as solvent as well as reagent for the zwitterionic hydroxy intermediates. Thus, it is possible to synthesize monomeric precursors with up to twelve methylene groups between the positive and the negative charge. A selection of these monomers has been successfully tested for their ability to polymerize using free-radical polymerization.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
