Research Abstract

Dendrimers, which consist of a core, repeating units, and functional terminals, are expected as materials with complex functionalities. The novel functionality also generates from the organization of dendrimers. In the present work, amphiphilic dendrimers with hydrophobic (n-hexyl) terminals and hydrophilic (hydroxyl, glycoside, or amine) terminals were synthesized, and the molecular assemblies at the solid-liquid (water) interface were examined. A dendrimer with n-hexyl/amine terminals displayed slightly less ability of assembly formation than a dendrimer with n-hexyl/hydroxyl terminals, but the ability was superior to that of a dendrimer with n-hexyl/glycoside terminals.
Self-assembled monolayer is one of organized molecular assemblies. Since we have found that carboxylic acid derivatives construct self-assembled monolayers as well as thiol derivatives, the monolayer preparation from a dendrimer with carboxylic acid terminals was examined. The dendrimer adsorbed more preferably on metal substrate than that with amine terminals. The excess adsorption depending on pH was observed, but the self-assembled monolayer does bot desorb from the substrate even after the rinse by water. It was confirmed that the monolayer formation proceeds owing to the interaction of carboxylic acid with metal substrate.
