The authors prepared the first Pt(II) metallosurfactants from a new family of linear surfactant phosphines Ph2P(CH2)nSO3Na {1 (n = 2), 2 (n = 6), and 3 (n = 10)}, which were synthesized by reaction between the halosulfonates X(CH2)nSO3Na and sodium diphenylphosphide. The metallosurfactants cis-[PtCl2L2] (L = 1–3) were obtained after reaction between the phosphines and PtCl2 in DMSO. All compounds were fully characterized by the usual methods {NMR (1H, 13C, 31P, 195Pt), IR, MS-ESI and HRMS}. By exploring the surfactant properties of phosphines 1–3 and their resp. Pt metallosurfactants cis-[PtCl2L2] (L = 1–3) through surface tension measurements, dynamic light scattering spectroscopy, and cryo-TEM microscopy, the authors were able to analyze the influence of the metal coordination on the critical micelle concentration (cmc) and the aggregation properties. The cmc values of Pt metallosurfactants were considerably lower than those obtained for the free phosphines 1–3. This behavior could be understood by an analogy between the structure of cis-[PtCl2L2] complexes and bolaform surfactants. The calculated values of area per mol. also showed different tendencies between 1–3 and cis-[PtCl2L2] complexes, which could be explained from the possible conformations of these compounds in the air-H2O interface. The study of aggregates by dynamic light scattering spectroscopy and cryo-TEM microscopy showed the formation of spherical disperse medium size vesicles in all cases. However, substantial differences were observed between the three free phosphines (the population of micellar aggregates increased with long chain length) and also between phosphines and their resp. metallosurfactants. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Application of 6294-17-3).
1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Application of 6294-17-3
