Background and Originality Content,Inclusion single crystals(IsCs)are characterized by the encapsulation of guest molecules within the crystal lattice of a host framework,resulting in,well-defined channels or cavities throughout the material. Host molecules can be broadly di.Videdinto wo main categories.i)The more widespreadgroup is unimolecular inclusion compounds where one host molecule interacts with one guest species.Familiar examples of this cate-gory include calixarenes,cyclodextrins,crown ethers,bai cavitands.cucurbituils,uoaciyclophanes,and various carcerands,ii) the other is multimoiecular inclusion caompounds where two or more host molecules are involved in forming cavities,channels,or layers in the crystal structure to accommodate guest molecules.Host molecules of,this kind include urea,choleic acis,Dianin's compound,etc.,and crystline porous materials such as metal-organic poliyhedrali and porous organic[18]cagesll are well-known examples.
