摘要：

Multifrequency phase and modulation fluorescence spectroscopy are used to study 1:1 inclusion complexes of β-cyclodextrin (βCD) with several anilinonaphthalene sulfonate (ANS) probes. Our time-resolved fluorescence results indicate that the inclusion complex is described most accurately by distributed fluorescence lifetime models. This indicates that the ANS probe is not in a single discrete environment within the cyclodextrin cavity but in an array of cyclodextrin-cavity environments all in equilibrium with one another. © 1990, American Chemical Society.
