When 2mg of the compound represented by the above formula (Ib-1) was dissolved in 0.5mL of chloroform and acetonitrile was slowly diffused therein by the vapor phase diffusion method, crystals were obtained as transparent masses, and the structure diagram is shown in FIG. 5. Single crystal X-ray diffraction experiments show that a 1:2 complex structure is formed between a guest molecule chloroform and a macrocyclic host. A chloroform molecule is entirely enclosed by the barrel-shaped cavity of the body. In addition, the molecule is also brought close to another chloroform molecule by intermolecular forces and the chloroform molecule is pulled to the edge of the barrel-shaped cavity. The main forces for maintaining the structure are the non-classical hydrogen bond of chlorine atom and hydrogen atom on the main body, the lp of chlorine atom to aromatic ring…Pi interactions and dipole-dipole interactions between chloroform molecules.
