The stability of the vase-like conformation of a deep cavitand 1 with four imidazoquinoxaline flaps was studied in CDCl₃/CD₃OD by ¹H NMR method. The annular tautomerism of cavitand 1·4MeOD in CDCl₃/CD₃OD (1:9 v/v) was investigated by ¹H NMR and the free energy of activation (ΔG^‡₂₆₈) of this process was measured as 12.9 kcal/mol at a coalescence temperature of 263 K. The inclusion complexation of 1 with various rod-like fatty amides and fatty esters resulted the formation of host-guest complexes in 1:1 stoichiometry where the alkyl chain of guests are coiled within the cavity and stabilized by CH/π interactions with the enlarged aromatic π surfaces of imidazoquinoxaline flaps.

通过¹ H NMR方法在CDCl ₃ / CD ₃ OD中研究了具有四个咪唑并喹喔啉瓣的深腔体1的花瓶状构象的稳定性。通过¹ H NMR研究了Cavitand 1 ·4MeOD在CDCl ₃ / CD ₃ OD（1：9 v / v）中的环状互变异构现象，该过程的活化自由能（ΔG ^‡ ₂₆₈）为12.9 kcal / mol。在263 K的聚结温度下。1的夹杂物络合 与各种棒状脂肪酰胺和脂肪酯形成的主客体络合物以1：1的化学计量比形成，其中来宾的烷基链盘旋在空腔内，并通过CH /π与咪唑并喹喔啉瓣的扩大的芳族π表面相互作用而稳定。
