Fluorosurfactants are amphiphilic materials which provide performance benefits not achievable by conventional surfactants, i.e. they efficiently reduce the surface tension of solvent- and water-based systems. Within the last decade the usual fluorosurfactants based on perfluorooctanesulfonic acid (PFOS) or perfluorooctanoic acid (PFOA) are known as global pollutants and are found in humans and wildlife around the world. Recently, we have developed a convenient procedure to synthesize fluorosurfactants, which consist of structures with short perfluoroalkyl chains and a hydrophilic moiety. In this presentation the synthesis of bis(perfluoroalkyl)phosphinyl amides, RF2P(O)NRR' [1] and the first performance tests of this new generation of fluorosurfactants will be discussed.
