| Abstract;Lithocholic acid does not form inclusion crystals. However, we recently reported that amide derivative of lithocholic acid, formed inclusion compounds with many organic substantces. Here we report that inclusion phenomena of lithocholarmide with 30 aliphatic alcohols form methanol to hexanols. As a result, it can be seen that the amide included 13 alcohols among them. The large and bulky alcohols with four to six carbon atoms are included. X-ray diffractions indicate that host assemblies of lithocholamide form three polymorphs, type A, type B, type C. In all polymorphs, the host molecules arrange in bilayers, which are stacked so as to leave channels accommodating the guests. However, the inclusion spaces change in response to for bulkiness of the guest. Accordingly, the large cavities and guest-depended polymorphism enables lithocholamide to include large alcohols.
