Abstract

We have recently found that ethanol molecules form hydrogen-bonding molecular macroclusters extending from silanol groups on silica surfaces in nonpolar solvents such as cyclohexane. Strong attractive force appears between two surfaces adsorbing ethanol macroclusters and this force decreases by increasing ethanol concentration from 0.1 mol% to 2.0 mol%. This attraction force between ethanol macroclusters was used to form two dimensional nano-stuructures of gold nanoparticles, modified with HS(CH₂) ₁₁OH, on the glass substrate at various ethanol concentrations in cyclohexane. Surface observation employing AFM showed this nano-structure depended on particle concentrations and the attractive interaction between the ethanol macroclusters.
