NaBPhinf>4/inf> acts as a surfactant in water, decreasing surface tension and forming micelle-like structures in water/NaBPhinf>4/inf> mixtures.
Abstract
Sodium tetraphenylborate (NaBPh4) induces the highly ordered structures, such as multi-lamellar vesicles, in the water/3-methylpridine mixture. In this sense, NaBPh4 can behave as a surfactant in the organic solvent mixtures. It is then expected that NaBPh4 also behaves as a surfactant in neat water. To examine this assumption, the effects of NaBPh4 on the surface structure and the bulk structure of the water were measured. It was shown that the surface tension of water decreases by dissolving NaBPh4. Additionally, micelle-like structure was confirmed in the water/NaBPh4 mixtures.
