Abstract Summary: Lamellar single crystals of V‐amylose have been prepared from dilute solutions in the presence of various complexing agents (isopropanol, thymol, linalool, terpineol, α ‐naphthol and quinoline). They were characterized by means of electron microscopy imaging and electron crystallography. Crystals of the V isopropanol ‐type were more frequently obtained even with complexing molecules with different sizes and chemical structures. α ‐naphthol and quinoline formed crystals involving 8‐fold amylose helices. Flower‐like “pseudo‐spherocrystals” of lamellar units were observed when the crystallization was carried out at higher amylose concentration.
