a, c PXRD patterns of QL-COF-1 and QL-COF-2. Comparison of the experimental PXRD patterns (red) with the Pawley refined pattern (black), simulated pattern for AA stacking (green) and difference plot (blue). b, d Views of AA stacking model for QL-COF-1 and QL-COF-2. e The 13C NMR spectra of QL-COF-1 (green), QL-COF-2 (orange) and model compound (blue). All above date were measured on powder samples.
