Abstract
Supramolecular light-harvesting antenna systems were constructed by using p
olyrotaxanes, in which cyclodextrin (CD) rings of alpha -CD and naphthalene
(energy donor)-appended alpha -CD are threaded by a poly(ethylene glycol)
chain with anthracene (energy acceptor) units at both ends (5-8). The effec
ts of the component ratio of the polyrotaxanes on the efficiencies of energ
y migration and energy transfer were examined by fluorescence emission and
excitation spectra and anisotropy and by fluorescence decay measurements. T
he observed results were explained by using the Forster mechanism.
