| We show how to make glow sticks and go through all the chemicals needed as well as how to make different colors. We also talk about the chemistry and scientifically research a proposed mechanism. To make the glow stick mix together the following: 10mL Diethyl Phthalate (solvent) 3mg of fluorescent dye (see below) 50mg TCPO (see below) 100mg sodium acetate 3mL 30% hydrogen peroxide (add last to start reaction) The fluorescent dye can be 9,10-bis(phenylethynyl)anthracene for green, Rubrene for yellow, 9,10-diphenylanthracene for blue, and rhodamine B for red. TCPO is expensive to buy but can be made for much cheaper by following the directions in our previous video: www.youtube.com The chemicals, including the ones to make TCPO were purchased from alfa aesar: www.alfa.com The Rhodamine B and Rubrene dyes were instead purchased from sigma Aldrich www.sigmaaldrich.com The dyes and TCPO are carcinogenic and gloves should be worn when handling them. The TCPO and sodium acetate amounts can be varied considerably and still obtain good light. Smaller quantities tend to be dimmer and decay faster, while larger quantities last longer. For those of you higher level individuals that actually do want to know the mechanism for this process, please refer to this article: pubs.acs.org |
