In the Laboratory
Spectral Characterization of a Novel Luminescent Organogel

Abstract
An experiment is described utilizing a novel luminescent organogel. The gel's unique cross-linking structure has been used by other scientists as a template for the synthesis of nanosize magnetic materials. This cross-discipline laboratory was designed for chemistry majors taking physical chemistry or instrumental analysis during their third or fourth year. Students are exposed to various topics in spectroscopy such as the acquisition of excitation and emission spectra, luminescence as well as quenching, and Stern–Volmer plots. In addition, the discussion of surfactants, concepts such as reversed micelles, and hydrogen bonding will be brought to life as students synthesize the gel themselves.
Supplement
Instructions for the students and notes for the instructor are available.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
