In this study, we prepared an amphiphilic silsesquioxane (Am-SO) capable of forming reverse micelles. The synthesis was performed by the sol-gel reaction of a mixture of triethoxysilane containing an ether-chain and 3-aminopropyltrimethoxysilane in aqueous hydrochloric acid. The gel permeation chromatog. measurement of Am-SO in chloroform eluent (<1.0 w/v%) showed a correlation between the excluded volumes (mol. weights of the peak tops; Mp's) and concentrations, i.e., higher Mp's at higher concentrations On the contrary, the Mp's of Am-SQ in chloroform were constant at concentrations above 1.0 w/v%. These results indicated that Am-SQ could form reverse micelles at a relatively high concentration in chloroform. Furthermore, dynamic fight scattering measurements of the Am-SO chloroform solutions having various concentrations were performed. The average particle size (diameter) of the 0.5 w/v% Am-SQ solution was assessed to be 0.86 ± 0.13 nm, whereas those in the solutions above 1.0 w/v% concentration were 8-11 nm, indicating that Am-SQ afforded stable reverse micelles at concentrations above 1.0 w/v%. In addition, the reverse micelles of Am-SQ in chloroform could incorporate ionic hydrophilic dyes, such as tetraphenylporphine tetrasulfonic acid and 1,3,6,8-pyrenetetrasulfonic acid tetrasodium salt, as confirmed both visually and by UV-Vis spectroscopy. Journal of Nanoscience and Nanotechnology published new progress about Amphiphiles. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, COA of Formula: C19H34O2.
