  • Poly-halogenated triazapentadiene compositions
    Patent number: 7893288
    Abstract: A new class of fluorinated or polyhalogenated triazepentadienes are disclosed. The synthesized triazapentadienes are thermally stable, soluble in typical solvents and have several metal binding sites for complexation with metal ions. The compounds are prepared as colorless crystalline solids. Synthesis takes advantage of a reaction with triethylamine. Synthesized triazapentadienes (with and without complexed metals) inhibit bacterial growth of both Gram positive and Gram-negative bacteria.
    Type: Grant
    Filed: January 20, 2010
    Date of Patent: February 22, 2011
    Assignee: Board of Regents, The University of Texas System
    Inventors: H. V. Rasika Dias, Lorraine G. van Waasbergen, Jaime A. Flores
