TEM images of a the metastable species 1AggI and after aging for b 50 min and c 180 min to obtain the thermodynamically stable species 1AggII. d High-resolution TEM image showing the lattice fringes and e the corresponding SAED pattern of 1AggII. f–h HAADF-STEM image and the corresponding EDS for elemental mapping of 1AggII. AFM images of i 1AggI and j 1AggII. Inset of i: DLS results of 1AggI. Inset of j: the height profile of 1AggII. The height was the average value along the white dash line. The samples were obtained by drop-casting the H2O/DMF (24:1, v/v, c = 3.00 × 10–5 M) solution of 1 on copper grid for TEM experiments and on silicon wafer for AFM experiments. Experiments were repeated at least three times with similar results.
