The Preparation of a Fluorescent Dye: A Microscale TLC Experiment
Daniel S. Calimente, Shannon M. Strand, Shao-Chieh Chang, and David E. Lewis Department of Chemistry & Biochemistry, South Dakota State University, Box 2202, Brookings, SD 57007-0896
This paper describes an experiment that allows the instructor to introduce TLC as a technique for analyzing reaction mixtures by monitoring the formation of a fluorescent dye. The experiment also illustrates the effects of eluting solvent on elution order. The visual impact of the fluorescent compounds on visualization under long-wavelength (365 nm) ultraviolet light constitutes a major improvement over most other TLC experiments.
