Featured Molecules November 2004

""
The featured molecules for this month are from “Parallel Combinatorial Synthesis of Azo Dyes: A Combinatorial Experiment Suitable for Undergraduate Laboratories” by Benjamin W. Gung and Richard T. Taylor. The principle of combinatorial chemistry is illustrated by generating a relatively large number of colorful dyes using only one common reaction, the diazo coupling, and two common reactants with small variations.

In addition to the static image, two fully manipulable versions (Jmol, MDLChime) of these molecules appear below. (The Jmol versions may take a few extra seconds to load, based on the speed of your Internet connection.)
