抄録

Octa(3-aminopropyl) polyhedral oligomeric silsesquioxane (POSS-NH2), adopting a rigid cubic structure, have been employed as a stabilizer for gold nanoparticles (AuNPs). The AuNPs possessing POSS-NH2 were stable enough to tolerate evaporation by incubating for 24 h after the preparation. Changing molar ratio of POSS-NH2 controlled the size of particle aggregates. In addition, the affinity of the AuNPs to organic solvents was changed via Michael addition with methyl acrylate to the amino groups on POSS-NH2. Redispersibility, aggregation control, and surface modification were successfully achieved with POSS-NH2 as a multifunctional single molecule.
