There is an ongoing interest in research focused on developing polymeric organic-light-emitting-devices (OLED) to replace inorganic devices. Compared to inorganic devices, OLEDs could present better properties such as higher efficiency, lower cost and simpler device fabrication. In an attempt to get a device with high efficiency, the hole transporting group and the electron transporting group were combined into a polymer to make an individual 'particle device'. The idea was to create a polymer particle containing both charge transporting moieties via emulsion polymerization. In this presentation, different techniques will be described that were used to determine the stability and the surface characterization of the colloidal particles (zeta potential, conductometric titration for the surface charge density). Equally as important for OLED devices is the control of the energy profile of the material, or the transferred energy within the device. Cyclic voltammetry was used to measure the electrochemical behavior of the charge transporting particles. To this end, cyclic voltammetry is very useful to determine the HOMO-LUMO energy levels and the band gap energy.
