Study on the structure and properties of inclusion complexes of large ring cyclodextrin and aromatic compounds

We successfully used co-precipitation to integrate four common aromatic compounds with different functional groups into macrocyclic dextrin, and we provided a detailed description of the inclusion complexes that occurred. Combining X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and nuclear magnetic resonance hydrogen spectroscopy (¹H NMR) allowed for confirmation of the inclusion complexes' formation. The thermal stability of the aromatic compounds is also supported by the inclusion complexes' higher structural stability. In the industrial and culinary sectors, LRCD is anticipated to function effectively as a solid matrix carrier for encapsulating aromatic chemicals.
