The study of single‐molecule single‐crystals of isotactic polystyrene was carried out by scanning tunneling microscopy (STM) and transmission electron microscopy (TEM). It was shown that STM provided more information than TEM. By means of STM, the single‐molecule single‐crystals were found even in the case of aggregation. Regular strips were also found on the top surface of single‐molecule single‐crystals. This seems to imply regular adjacent folding.
