β-Cyclodextrin conjugates with selectively methylated rims The current doctoral thesis focuses on studying cyclodextrin conjugates with selectively methylated rims and testing their potential applicability for solubility enhancement and guest- specific complexation. This work's principal aim is to develop new synthetic methods for the preparation of monofunctionalized β-cyclodextrin derivatives with selectively methylated rims and their further transformations into operating conjugates. The thesis is divided into four sections - preparation of monoazido-β-cyclodextrin derivatives with selectively methylated rims and some conjugates from them; direct transformation of the prepared azides into corresponding monoamines and monohalides that enables the synthesis of other types of conjugates; testing the potential of the prepared conjugates for tetracene solubility increase in different media and selective binding of one component from a mixture of steroid substances; finally, the work explores the complexation of some noradamantane molecules with natural cyclodextrins and the phenomenon of guest's signals splitting in their 13 C-NMR spectra. Keywords: cyclodextrin conjugates, bisCDs, selective methylation, selective binding, solubility enhancement
