Abstract We report here a one-pot synthetic method for the synthesis of a bisester-functionalized copillar[5]arene (BECP5A) with yield up to 20%. The properties of BECP5A in solution and in solid state were deeply investigated with the aid of 1D and 2D NMR spectra and X-ray diffraction, showing that this molecule has a fully self-included conformation in chloroform and partial self-inclusion in DMSO, and the compound has an asymmetrical structure with only one self-included side in the cavity of pillar[5]arene in the solid state. This compound will be used as the precursor of complex systems such as polymers and mechanically interlocked molecules.
