TEM imaging and structure assignment of PNCs in I-MOF-5 synthesis at 0.01 M of Zn2+ for 21 h. a Ten SMART-EM images out of 80 video frames of a cubic PNC made of IBDC rotating in a stochastic manner (methanol wash). The original video is Supplementary Movie 6. b Time-dependent change of the standard deviation of the pixel values in the video frames. Five high contrast frames, shown in a, are indicated by red arrows and five low contrast frames by black arrows. c A model structure of the cubic PNC at 10.0 s, where the 12 iodine atoms are numbered and their positions in 2-D projections are highlighted. d An isometric projection of the cube at 10.0 s, where 12 spots of iodine atoms are highlighted by red circles. e A simulated image and f a Z2A model corresponding to e. g A dimeric projection at 34.0 s, h simulated image, and i Z2A model corresponding to h. Figures c, f and i share the same numbers for assignment of the 12 iodine atoms
