  • Publication number: 20220085373
    Abstract: The present disclosure provides the use of a biomolecule, flavin, appended to a polymerizable unit that can then be polymerized to form an electroactive active polymer. The polymer and the flavin unit are comprised of an organic material containing C, H, N, and O atoms. The electroactive functionality is related to the double bonds that are present in the flavin unit that are appended to a non-electroactive backbone. This appended unit is rendered insoluble in the electrolyte of the discussed secondary battery unit. Several different molecular structures are disclosed exhibiting efficacy as energy storage medium in energy storage devices. Compounds have also been synthesized from which these different energy storage molecular structures are produced.

  • Publication number: 20200339816
    Abstract: Water soluble light harvesting multichromophores having a plurality of pendant chromophore groups are provided. Water soluble light harvesting multichromophores according to certain embodiments are polymers that include a polymeric backbone having norbornene repeat units, a pendant water solubilizing group component and a pendant chromophore component. Polymeric tandem dyes based on the subject multichromophores are also provided that further include an acceptor fluorophore linked to a norbornene repeat unit of the polymeric backbone and configured in energy-receiving proximity to at least one pendant donor chromophore group of the light harvesting multichromophore. Also provided are labelled specific binding members that include the subject polymeric tandem dyes. Methods of evaluating a sample for the presence of a target analyte and methods of labelling a target molecule in which the subject polymeric tandem dyes find use are also provided.
