Just to correct the name. DNPO is a diester and hence should have a space in the name and specify there are two. Also the location of the nitro groups should be specified. It is bis(2,4-dinitrophenyl) oxalate (preferred IUPAC name). The more systematic ethanedioate is perhaps preferred by schools.

Hi,
November's MOTM is dinitrophenylethanedioate, or DNPO for short. It's the molecule which forms the basis of Cyalume "light sticks" used by divers for emergency and underwater lighting, fishing lures and various novelty items such as glow necklaces. Since 1980 molecules like these have become widely used as analytical tools for trace analysis and are currently the most sensitive and versatile chemiluminescence detection method for liquid chromatography.
The MOTM page has been adapted from a set of pages at Leeds University written by Daniel Ormsby called "The Delights of Chemistry", in which various spectacular and visually impressive chemical reactions are described. This MOTM page is available in HTML, Chime and Chemsymphony versions.
