Abstract

In this work, we report the syntheses and characterization of a new crystalline inclusion compound ofα-cyclodextrin using diquinuclidinium cation([Q2H]+)like guest. Elemental analysis,13C CP-MAS NMR spectroscopy and powder X-ray diffraction analysis confirm the inclusion process. The guest specie[Q2H]+corresponds to the adduct of a heterocyclic base with its conjugated cation in a symmetric linear arrangement[Q–H–Q]+. This complex[Q2H]+appears to be held in the host cavities only by weak van der Waals interactions.
