Abstract

original image

Hold and connect! Inclusion of a bridging ligand into cyclodextrin (CD), followed by the addition of TbIII leads to a polyrotaxane-type metallosupramolecular polymer (see figure, L=4,4′-biphenyldicarboxylic acid). This polymer can recognize chirality and differentiate enantiomers by fluorescence and circular dichroism spectral changes.
