    • The miniemulsion polymerization using a conventional surfactant, sodium dodecyl sulfate also afforded the fluorescent polymer particles. In this report, we used the reactive surfactant since we preferred to minimize the micelle formation by the surfactant. Because, pyrenes can be located in such micelle and be concentrated to form the excimer

    • The diameter of PS/2-3 was smaller than that of PS/1. The pyrenes 1-3 are hydrophobic and could work as a hydrophobe in miniemulsion polymerization. In particular, relatively large amount of 1 might result in the larger diameter.

    • The measurement of fluorescence lifetimes of PS/1-3 without oxygen was difficult. The light-scattering by polymer particles disturbed monitoring the fluorescence emission of 1-3. The degassing by freeze-pump-thaw cycle is not available for emulsions and the careful nitrogen bubbling could not reject oxygen completely from the emulsions.
