β-Cyclodextrin is chemically modified to selectively introduce an acridinedione moiety on the primary face. The synthesis involves the substitution of one of the primary hydroxyl groups of β-cyclodextrin by a tosyl group which facilitates the introduction of an ethylene diamine modification which is finally condensed to a tetraketone. The acridinedione modified β-cyclodextrin thus obtained was fully characterized by IR, NMR and Mass spectrometry. The photophysical properties of the compound were also analyzed. The potential of the modified β-cyclodextrin to act as an energy donor in FRET was investigated with a suitable acceptor.
