Figure 2. (A) PXRD patterns of CPOF-4: comparison between the experimental (black) and Pawley refined (red) profiles, the refinement differences (blue), and the Bragg positions (green); (B) PXRD pattern analyses of CPOF-4-265 °C-X h (X = 12, 48, and 84) compared with the CPOF-4; (C) PXRD patterns of CPOF-4 and CPOF-4-265 °C-84 h: experimentally observed (solid line) and simulated based on eclipsed stacking modes (dashed line); (D) PXRD patterns of CPOF-4-265 °C-84 h: comparison between the experimental (black) and Pawley refined (red) profiles, the refinement differences (blue), and the Bragg positions (green); (E) Space-filling models of CPOF-4-265 °C-84 h. Carbon, gray; Nitrogen, blue; Hydrogen, white; (F) N2 adsorption/desorption isotherms of CPOF-4 and CPOF-4-265 °C-X h
