The chemical structure of the repeating units of the polyimides simulated in the present study: ODPA-P3 (a), aBPDA-P3 (b), and BPDA-P3 (c). The arrow marks vector P directed along the phthalimide planar moieties of the polyimide chains; its orientation relative to the nanotube axis was investigated. For clarity the vector P is shown only for the ODPA-P3 PI; for aBPDA-P3 and BPDA-P3 these vectors have been directed along the same fragments.
