A General Method to Prepare Halogen-Free Oxalate Diesters for Peroxyoxalate Chemiluminescence Demonstrations

// Thursday, July 25, 2019 • Iain Smellie

Introduction: Chemiluminescence demonstrations that use peroxyoxalate “glowstick” systems are very popular in a variety of lecture demonstrations and classroom activities^1-3. These reactions are very eye catching and easy to do; however, until recently, the range of oxalate diesters available has been limited.

DIY Vapor Catalyzed Chemiluminescence

I recently watched a video in which a chemist (who goes by the nickname “NurdRage”) activated a chemiluminescent reaction by vapor deposition. You can see a short clip of this experiment below:

Experiments with Expo Markers

Doug Ragan’s post on Expo neon markers got me thinking about how I’ve used these markers in my classroom. By simply using these markers, a small UV/violet LED and a white lightstick, you can teach your students a bit about fluorescence and chemiluminescence.
