  • Publication number: 20210403647
    Abstract: Compositions and methods related to conducting polymeric compositions that can be used for the storage of electrical energy are generally provided. In some embodiments, the composition comprises redox active polymers comprising an electrophilic nitrogen containing heterocycle and an electron rich aromatic compound. In some embodiments, the composition comprises a triazine-based polymer. The electroactive polymers may be formed, in some cases, by polymerizing an electrophilic nitrogen containing heterocycle-based unit with an electron rich aromatic compound in the presence of heat and an acid-based catalyst. The resulting electroactive polymers may be suitable as polymer films for use as electrodes in energy storage devices. The polymer films disposed as electrodes can improve the energy density of such devices.

  • Patent number: 9997706
    Abstract: A method for preparing semiconductor nanocrystals is disclosed. The method comprises adding a precursor mixture comprising one or more cation precursors, one or more anion precursors, and one or more amines to a ligand mixture including one or more acids, one or more phenol compounds, and a solvent to form a reaction mixture, wherein the molar ratio of (the one or more phenol compounds plus the one or more acids plus the one or more amine compounds) to the one or more cations initially included in the reaction mixture is greater than or equal to about 6, and heating the reaction mixture at a temperature and for a period of time sufficient to produce semiconductor nanocrystals having a predetermined composition. Methods for forming a buffer layer and/or an overcoating layer thereover are also disclosed. Semiconductor nanocrystals and compositions including semiconductor nanocrystals of the invention are also disclosed.
