A molecular bowl with barium ion covering one portal of decamethylcucurbit[5]uril as a‘metal-ion- bottom’has been synthesized. The structure of the molecular bowl has been confirmed by the single crystal X-ray diffr...
Crystals of a new 1,4-dimethyl cucurbituril(TMeQ6) with Silver(I) ion were synthesized, and the structure was determined by X-ray diffraction technique. There are two kinds of TMeQ6 A and B which formed molecular enca...
