Embodiments of the presently disclosed technology provide a synergistic combination of a conjugated open-shell donor-acceptor polymer with a carbon-based compound (e.g., reduced graphene oxide) to produce a composite electrode material which demonstrates state-of-the-art capacitance and potential window, with excellent kinetics and cycle life. The conjugated open-shell donor-acceptor polymer may comprise a plurality of alternating electron-rich monomers (i.e., donors) and electron-deficient monomers (i.e., acceptors) bonded together via a conjugated backbone. The conjugated backbone may comprise a connection of n-orbitals of the plurality of monomers in alternating single and double bonds that facilitates unpaired electron delocalization—thereby stabilizing charge for the polymer. The carbon-based compound of the composite electrode material may provide porous, conductive scaffolds for the composite electrode material, resulting in electrodes scalable to microns-thick films with fast kinetics.

Water-soluble fluorescent polymeric dyes and polymeric tandem dyes are provided. The polymeric dyes include a water solvated light harvesting multi-chromophore having a conjugated segment of aryl and/or heteroaryl co-monomers. The molar ratio of the co-monomers can be adjusted to provide beneficial technical properties, such as increased water solubility and improved absorption and emission spectra. For instance, the conjugated segment can have a first co-monomer substituted with a water-soluble group (WSG) and a second co-monomer, wherein the first co-monomer is in an amount that is equal or greater than the amount of the second co-monomer, multi-chromophore. The polymeric tandem dyes further include a signaling chromophore covalently linked to the multi-chromophore in energy-receiving proximity therewith. Also provided are aggregation-resistant labeled specific binding members that include the subject water-soluble polymeric dyes. Methods of evaluating a sample for the presence of a target analyte and methods of labeling a target molecule in which the subject polymeric dyes find use are also provided. Systems and kits for practicing the subject methods are also provided.
