The crosslinked polymers have at least one redox active monomeric moiety having a redox potential of 0.5 V to 3.0 V with reference to Li/Li.sup.+ electrode potential under standard conditions or 2.54 V to 0.04 V vs. SHE and has a carbocyclic structure and at least one carbonyl group or a carboxyl group on the carbocyclic structure. The crosslinked polymers also include at least one comonomeric moiety with at least one of the at least one redox active monomeric moiety and/or the at least one comonomeric moiety has a denticity of three to six corresponding to a three to six connected network polymer, and provide stable, high capacity organic electrode materials.

Hydrocarbon proton exchange membranes are disclosed that are composed of a material including a hydrophobic main chain, and acidic side chains. The main chain includes a polyaryl structure that is substantially free of ether linkages and also includes a fluoromethyl substituted carbon. The acidic side chains include a hydrocarbon tether terminated by a strongly acidic group, such as a fluoroalkyl sulfonate group. Chemical stability of the material is increased by removing the ether linkages from the main chain. The hydrophobic main chain and substantially hydrophilic side chains create a phase-separated morphology that affords enhanced transport of protons and water across the membrane even at low relative humidity levels. These materials are advantageous as membranes for use in fuel cells, redox flow batteries, water hydrolysis systems, sensors, electrochemical hydrogen compressors, actuators, water purifiers, gas separators, etc.
