    Nanoscale

    A nonconjugated methacrylate terpolymer containing carbazole moieties (electron donors), 1,3,4-oxadiazole moieties (electron acceptors), and Coumarin-6 in the pendant groups was synthesized via free radical copolymerization of methacrylate monomers containing the respective functional groups. The terpolymer was formed into 57 nm particles through a mini-emulsion route. For a thin 100 nm film of the fused particles sandwiched between an indium-tin oxide (ITO) electrode and an Al electrode, the…

    A nonconjugated methacrylate terpolymer containing carbazole moieties (electron donors), 1,3,4-oxadiazole moieties (electron acceptors), and Coumarin-6 in the pendant groups was synthesized via free radical copolymerization of methacrylate monomers containing the respective functional groups. The terpolymer was formed into 57 nm particles through a mini-emulsion route. For a thin 100 nm film of the fused particles sandwiched between an indium-tin oxide (ITO) electrode and an Al electrode, the structure behaved as a nonvolatile flash (rewritable) memory with accessible electronic states that could be written, read, and optically erased. The device exhibited a turn-on voltage of ca. -4.5 VDC and a 10(6) current ratio. A device in the ON high conductance state could be reverted to the OFF state with a short exposure to a 360 nm light source. The development of semiconducting colloidal inks that can be converted into electroactive devices through a continuous processing method is a critical step in the widespread adoption of these 2D manufacturing technologies for printed electronics.

Patents

  • Color-tailored polymer light emitting diodes including emissive colloidal particles and method of forming same

    Issued US 8003008

    Color-tailored and white-light emitting polymer colloid-based OLEDs are disclosed. Devices include electroluminescent (EL) colloidal conductive polymer systems that can include EL dyes or other EL materials. Systems can sequester multiple EL components in different colloids in a single emissive layer of an EL device with little or no appreciable energy transfer between colloids. Devices can exhibit tailored emissions over a broad range of wavelengths through mixing of, e.g., red, green and blue…

    Color-tailored and white-light emitting polymer colloid-based OLEDs are disclosed. Devices include electroluminescent (EL) colloidal conductive polymer systems that can include EL dyes or other EL materials. Systems can sequester multiple EL components in different colloids in a single emissive layer of an EL device with little or no appreciable energy transfer between colloids. Devices can exhibit tailored emissions over a broad range of wavelengths through mixing of, e.g., red, green and blue PLED colloids. Disclosed methods including incorporation of one or more electroluminescent dyes into a semiconductive EL polymer colloid that can isolate the dyes and prevent energy transfer while retaining individual color emission.
