Abstract
Preparation of organic-inorganic hybrid architectures was accomplished on a copper foil surface immersed in various aqueous solutions of formamide and aniline. Beautiful “flowers” (spherically folded crystals) as well as “buds” and “petals” were observed on the copper surface in an aqueous solution of formamide alone. These crystals were composed of nanosheets of copper hydroxide hydrate, Cu(OH)2・H2O. The petal-like crystals appeared to aggregate, resulting in the flower-like spherical forms, via the bud-like structures. When the copper foils were immersed in aqueous formamide and aniline, spherical particles of polyaniline were deposited on the copper surface. There were no hybrid structures consisting of copper and aniline under the present conditions.
