a Simulated molecular structure of PyTTA-TPA COF based on AA-stacking mode. b Theoretical and experimental GIWAXS of the PyTTA-TPA COF film with a thickness of ~30 nm. c TEM of the PyTTA-TPA COF film with a thickness of ~13 nm. Scale bar 50 nm. d, e TEM of the PyTTA-TPA COF film captured from regions in c. Scale bar 10 nm. The inset showed the fast Fourier transformation (FFT) patterns.
