Thin-Layer Chromatography. Chiral stationary phases have been used less extensively in tic as in high performance Hquid chromatography (hplc). This may, in large part, be due to lack of avakabiHty. The cost of many chiral selectors, as well as the accessibiHty and success of chiral additives, may have inhibited widespread commerciali2ation. Usually, nondestmctive visuali2ation of the sample spots in tic is accompHshed using iodine vapor, uv or fluorescence. However, the presence of the chiral selector in the stationary phase can mask the analyte and interfere with detection (43).

The concentrations of the different members of a DCL depend on the physical and chemical environment of the respective system (pH, solvent, concentration of target molecules, etc.). The Ubrary composition is therefore a characteristic feature of the respective environment If the DCL composition can be transduced into a signal output, it is possible to use the DCL as a sensor. Typically, DCLs are analyzed by nuclear magnetic resonance spectroscopy or high-performance hquid chromatography. For sensing purposes, however, faster and cheaper analysis methods such as fluorescence or ultraviolet-visible (UV-Vis) spectroscopy are preferred. These techniques can be used if the DCL is composed of compounds with different color or fluorescence properties (Figure 7.1).
