From: β-cyclodextrin mediated construction of porous helical nanoribbons from oligoaniline derivatives
Figure 4. (Left) FTIR spectra and (Right) selected 1H NMR spectra of (A) oligoanilines obtained with 12 h polymerization in the absence of β-CD. β-CD mediated polymerization product at various polymerization times: (B) 1 h; (C) 3 h; (D) 5 h; and (E) 12 h. (F) β-CD. FTIR: Fourier-transform infrared spectroscopy; NMR: nuclear magnetic resonance; β-CD: β-cyclodextrin.
