AbstractMonodisperse colloidal Au nanospheres (ca. 7 nm) in hexane are prepared in quaternary CTAB/n-pentanol/hexane/water reverse microemulsion (CTAB stands for cetyltrimethylammonium bromide). Their self-assembled linear/circular arrangements and polyaniline (PANi)-induced hexagonal patterns are observed on carbon-coated copper grids by TEM. The results are compared with those obtained in CTAB/n-butanol/octane/water reverse microemulsion. The homogeneity in size and shape of our as-made Au nanoparticles observed in TEM is attributed to the compact CTAB/n-pentanol interfacial film and high volatility of hexane. © 2003 Elsevier Science B.V.
