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.

The azopolymer includes a plurality of monomer units containing isoindigo with R.sup.1 and R.sup.2 substituent groups, wherein R.sup.1 can be one or more C1 to 30 hydrocarbons; and R.sup.2 can be H or F. The azopolymer can have a number average molecular weight (M.sub.n) of 4 to 20 kDa; a weight average molecular weight (M.sub.w) of 12 to 50 kDa; and a poly dispersity index (PDI) of 2 to 3. The polymer can further have selected maximal wavelengths (λ.sub.max) of 481 to 709 nm and electrochemical reduction events of −0.4 to −1.0 V against an Ag/AgCl reference electrode.

Embodiments may relate to a microelectronic package comprising: a die and a package substrate coupled to the die with a first interconnect on a first face. The package substrate comprises: a second interconnect and a third interconnect on a second face opposite to the first face; a conductive signal path between the first interconnect and the second interconnect; a conductive ground path between the second interconnect and the third interconnect; and an electrostatic discharge (ESD) protection material coupled to the conductive ground path. The ESD protection material comprises a first electrically-conductive carbon allotrope having a first functional group, a second electrically-conductive carbon allotrope having a second functional group, and an electrically-conductive polymer chemically bonded to the first functional group and the second functional group permitting an electrical signal to pass between the first and second electrically-conductive carbon allotropes.
