Figure 3. FESEM images of the nanostructures assembled from β-CD mediated oligoaniline derivatives at different polymerization times: (A) 1 h; (B) 3 h; (C) 5 h; (D) 9 h; and (E) 12 h. (F) A cartoon image of PHNR. FESEM: Field emission scanning electron microscope; β-CD: β-cyclodextrin; PHNR: porous helical nanoribbon.
