  • Pi-conjugated organoboron polymers in thin-film organic electronic devices
    Patent number: 8097348
    Abstract: Pi-conjugated organoboron polymers for use in thin-film organic polymer electronic devices. The polymers contain aromatic and or unsaturated repeat units and boron atoms. Pi-conjugated organoboron polymers which are end capped, derivatized with solubilizing groups or both exhibit improved solubility and handling properties beneficial for the formation of thin films useful for device fabrication. The vacant p-orbital of the boron atoms conjugate with the pi-conjugated orbital system of the aromatic or unsaturated monomer units extending the pi-conjugation length of the polymer across the boron atoms. The pi-conjugated organoboron polymers are electron-deficient and, therefore, exhibit n-type semiconducting properties, photoluminescence, and electroluminescence.
    Type: Grant
    Filed: March 19, 2007
    Date of Patent: January 17, 2012
    Assignee: TDA Research, Inc.
