Enhanced multidimensional luminescence measurements through cyclodextrin complexation

Abstract

The authors discuss the use of CDxs (Cyclodextrins) to enhance selective detection via EEM (Excitation Emission Matrix) measurements. Particular emphasis will be placed on the enhanced measurement of luminophors complexed with CDxs in the presence of select alcohols and quenchers. In addition, the use of solvent extraction and data analysis to reduce the dimensionality of the acquired EEM will be discussed. The use CDxs and quenchers can produce a single- or dual-component system from a more complex mixture, which can then be used as model component spectra. This type of data analysis scheme is presented and discussed. In this study, CDxs are used as aqueous phase components to increase the solubility of PAHs in water and thus increase their aqueous extraction efficiencies.
