Encapsulation of thiophene oligomers in CNTs having various diameters. (a) HR-TEM images of 0.5 and 1.4 nm diameter CNTs before 6 T encapsulation, and 1.0, 1.5, 1.7 and 2.2 nm diameter CNTs after encapsulation, along with structural models. (b) HR-TEM image of a CNT exhibiting a linear contrast with a length of more than 20 nm. All encapsulated samples were thermally annealed at 400 °C. (c) EELS spectrum of a CNT with encapsulated 6 T.
