Latest Patents

Swanson's latest patents focus on the development of acetylene-containing poly(p-phenyleneacetylene) (PPA) based light-emitting diodes. These LEDs are created by coating a hole-injecting electrode, typically an indium tin oxide (ITO) coated glass substrate, with a PPA polymer. The polymer can be a 2,5-dibutoxy or a 2,5-dihexoxy derivative of PPA, which is dissolved in an organic solvent. Following this, a layer of material capable of injecting electrons, such as aluminum (Al) or aluminum/calcium (Al/Ca), is evaporated onto the polymer to form a base electrode. The composition is then annealed to produce efficient electroluminescent (EL) diodes.
