Fig. 4

a Reconstructed ptychography phase image of an area with structural inhomogeneity: the majority of the imaged area corresponds to the structure of NU-1000, while the region marked with red dashed lines shows the presence of ‘extra clusters’ in hexagonal channels, relative to NU-1000. b Enlarged image from (a), showing a typical hexagonal channel of NU-1000, and the corresponding structural model. c Enlarged image from the region marked with red dashed lines in (a), revealing the presence of an ‘extra cluster’ in the hexagonal channel. The ‘extra cluster’ is inferred to be associated with the intergrowth of NU-1000 and NU-901. On the right is the proposed structural model. d The region marked with yellow dashed lines in (a) after orientation adjustment, illustrating missing linker defects (orange arrows) and the resultant triangular channel-terminated crystal surface (blue arrows), along with the corresponding structural model. Green Zr, red O, gray C, pink H.
