Fabiola Irene Lopez Vallejo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10000457
    Abstract: The present invention relates to a process of synthesis of certain ionic liquids di-polymerized based Radziszewsky type reaction, whereby primary amines containing at least one terminal functional group, for example —OH, aldehydes and a mineral or organic acid, react exothermically in a single step, thus resulting in an ionic liquid by condensation, then oxirane derivative molar quantities are added, by controlling the temperature and pressure a di-polymerized ionic liquid is obtained. The process of the present invention is advantageous because it provides a synthesis scheme for di-polymerized ionic liquids, primarily using short reaction times and high performance; this process can be further scaled for industrial production and it can accept alternative chemical precursors of lower cost.
    Type: Grant

  • Patent number: 8796450
    Abstract: A family of three 8-alkyl boron dipyrromethenes 1, 2, and 3 has been prepared. These compounds are characterized by emission in the green region of the electromagnetic radiation spectrum and exhibit an almost double laser efficiency than other commercial dyes and much greater photostability. The 8-alkyl boron dipyrromethenes are prepared by catalytic hydrogenation (reduction) of the corresponding 8-alkenyl boron dipyrromethenes, which are obtained by Liebeskind-Srogl coupling of thiomethylboron dipyrromethene with an alkenyl boronic acid.
