a, d, g Synthetic routes of (a) 1D Pery-COF, (d) 2D PL-Pery-COF, and (g) 2D ML-Pery-COF. b, e, h Powder X-ray diffraction (PXRD) of experimentally observed (green curves), Pawley refined (purple curves), their difference (black curves), and simulated AA (red curves) and AB stacking (blue curves) patterns of (b) 1D Pery-COF, (e) 2D PL-Pery-COF, and (h) 2D ML-Pery-COF. c, f, i DFTB-optimized crystalline structures viewed along the pseudo-quadratic pore of multilayered (c) 1D Pery-COF, (f) 2D PL-Pery-COF, and (i) 2D ML-Pery-COF (gray, carbon; blue, nitrogen; white, hydrogen). Solvothermal conditions: (i) HAc (6 M), o-dichlorobenzene (ODCB)/n-butanol (n-BuOH) (v/v = 4/1), 120 °C, 72 h, 77%; (ii) HAc (6 M), ODCB/n-BuOH (v/v = 3/1), 120 °C, 72 h, 86%; (iii) HAc (6 M), ODCB/n-BuOH (v/v = 3/1), 120 °C, 72 h, 82%.
