Organic light editting diode (OLED) utilize organic compounds that emit light after receiving electrical signals through electrical currents. The OLED is often commercially used to make displays for computers, smart-phones and various other electronic devices. However, when the components of OLED are photo-oxidized, impurities are created and the color of the display is changed. Compounds used for OLED typically have anthracene as basic structure. There are many compounds substituted at 9, 10 positions of anthracene. However, the effect of side chain on the oxidation rate has not been investigated yet. Therefore, in this study, samples having anthracene as core structure and 9 and/or 10 positions substituted with phenyl, methyl, or naphthyl groups were studied. The samples were oxidized with UV lamp under flow of oxygen gas. The observed rate of oxidation was different for each functional group. The Paper Spray Ionization (PSI) and Laser Desorption Ionization (LDI) mass spectrometry were used to analyze the oxidized samples. Theoretical calculations have been performed to explain the observed data.
