Fig. 4: Morphology and crystallinity of MTPA-CA:CNP147 molecular nanojunctions.

a–c, SEM image (a), high-angle annular dark-field scanning transmission electron microscopy image (b) and EDX mapping analysis of oxygen (purplish red) and fluorine (yellow) (c) of the MTPA-CA:CNP147 (4:6 wt/wt) molecular nanojunction formed by FNP. d, Cryo-TEM image of MTPA-CA:CNP147 nanojunction photocatalyst showing the fibre morphology. e, High-resolution cryo-TEM image of MTPA-CA:CNP147 nanofibres. Insets: crystalline domains in these nanofibres taken from the regions highlighted by the white squares. f,g, Filtered inverse fast Fourier transform images corresponding to the insets in e.
