Introduction
Supramolecular host-guest inclusion complexes, in which a small guest molecule becomes encapsulated within the internal cavity of a larger cage-like host molecule, have shown tremendous utility for molecular recognition, with a high degree of guest selectivity. (1) A wide range of applications of inclusion complexes have been reported, including chemical separations, (2) food and chemical industries, (3) drug delivery, (4) and fluorescence-based trace analysis. (5) Fluorescence spectroscopy has been shown to be an extremely sensitive and accurate experimental method for studying such inclusion systems, for example, extracting the binding constant K ...
