Abstract A series of bridged β-cyclodextrin (β-CyD) dimers possessing functional tethers of various lengths was synthesized in moderate yield by the treatment of 2, 2′-biquinoline-4, 4′-dicarboxylic dichloride with β-CyD or mono [6-oligo (ethylenediamino)-6-deoxy]-β- CyDs. The products were 2, 2′-biquinoline-4, 4′-dicarboxy-bridged bis (6-O-β-CyD)(8), N, N′-bis (2-aminoethyl)-2, 2′-biquinoline-4, 4′-dicarboxamide-bridged bis (6-amino-6- ...
