Guillermo SANTANA RODRIGUEZ 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).

  • White light emitting material and method of preparation and uses thereof
    Patent number: 10280366
    Abstract: The instant invention is related with new perimidine derivatives synthesized via direct condensation between naphthalene-1,8-diamine and itaconic or citraconic anhydrides at low temperature. The targeting itaco-perinone (IP) molecule formed via double low temperature cyclization has fluorescence properties emitting white light intensively. Besides, 9-methylene-8H-pyrrolo[1,2-a]perimidin-10(9H)-one is copolymerizable with several kind of organic monomer compounds via free radical mechanism maintaining the ability to emit white light even within the polymer film.
    Type: Grant
    Filed: June 21, 2016
    Date of Patent: May 7, 2019
    Assignees: Instituto Potosino DE Investigación Cientiffica y Technológica A.C., UNIVERSIDAD NACIONAL AUTONOMA de Mexico
    Inventors: Alejando Ricardo Femat Flores, David Rios Jara, Larissa Alexandrova, César Augusto Fernández Gijón, Guillermo Santana Rodriguez
