✦ Synopsis

In order to explore the possibility of external modi®cation of the binding ability through metal ligation, the inclusion complexation behavior of newly synthesized bis(b-cyclodextrin) (4) with an oligo(ethylenediamine) tether has been investigated with representative ¯uorescent dyes, 6-(p-toluidino)-2-naphthalenesulfonate (TNS) and 8-anilino-1-naphthalenesulfonate (ANS), and found to give enhanced binding and selectivity for the Cu(II)-ligated host (5).
