  • Publication number: 20230212102
    Abstract: The present invention provides a method for oxidizing pyrenes without any metal-mediated catalyst or reagent. In particular, the present invention provides a method for selectively oxidizing the K-region of pyrenes using a meta-free oxidizing agent to produce a pyrene 4,5-dione and/or a pyrene 4,5,9,10-tetraone compounds.

  • Publication number: 20220271235
    Abstract: The present invention provides methods for increasing stability and efficiency of organic perovskite materials for use in various electronic devices. In particular, methods of the invention use a non-peripheral substituted phthalocyanine for passivating defects in organic perovskite materials, thereby increasing its stability and efficiency relative to the same material in the absence of said non-peripheral substituted phthalocyanine.

  • Patent number: 9505770
    Abstract: Organic photovoltaic (OPV) devices are disclosed. An exemplary device has first and second electrodes and an organic, photovoltaically active zone located between the first and second electrodes. The photovoltaically active zone includes an organic electron-donor material and an organic electron-acceptor material. The electron-donor material includes one or more trivalent- or tetravalent-metal phthalocyanines with alkylchalcogenide ring substituents, and is soluble in at least one organic solvent. This solubility facilitates liquid-processability of the donor material, including formation of thin-films, on an unlimited scale to form planar and bulk heterojunctions in organic OPVs. These donor materials are photovoltaically active in both visible and near-IR wavelengths of light, enabling more of the solar spectrum, for example, to be applied to producing electricity. Also disclosed are methods for producing the metalated phthalocyanines and actual devices.
