摘要：
A novel branched fluorinated anion surfactant 4-(3,3,4,4,5,5,5-heptafluoro-2,2-bis-tri-fluoromethyl-pentyl)benzene lithium phosphonate was successfully synthesized via a four-step route using perfluoro-2-methyl-2-pentene as starting material. The surface activity was investigated. The result showed that the cmc value of the surfactant in water is about 1.5x10(-2) mol/L at 298 K and the surface tension of the aqueous solution is 19.2 mN/m at the cmc.
