Figure 2From: Shuttle-like supramolecular nanostructures formed by self-assembly of a porphyrin via an oil/water system SEM images of various nanostructures obtained from sample I. (A) SEM image of the irregular nanoarchitectures accompanied by several shuttle-like nanostructures. (B) High-resolution SEM image of the shuttle-like nanostructures. (C) SEM image of a hollow nanosphere. (D) SEM image of a nanotube. The aging time is 15 min.Back to article page
