Zusammenfassung:The polymer chains take a twofold helical structure of (-TTGG-) conformation, and the packing of the polymer chains enables each toluene molecule to occupy an isolated hole between the benzene rings of adjacent polymer chains. These molecular compounds are commonly transformed on heating between 120 and 150\0\C to another crystalline phase free from the guests, in which the polymer chains retain the helical structure.
