In a predominantly microporous structure such as YP-80F, the small pore environments limit the grafting causing the anthraquinone to attach directly to the carbon network (see solid-state NMR above). Whereas, for mesoporous carbons, the large pore environments could lead to anthraquinone molecules grafting onto themselves forming polymer-like multilayers, supported by a smaller chemical shift difference in the solid-state NMR experiments. The amount of quinones that are electrochemically accessible would be the same in the initial cycles, leading to similar adsorption capacities and anthraquinone loading as seen for mesoporous f-CMK-3 and predominantly microporous f-YP-80F. However, in long cycling experiments, multilayers in conjugated systems have been reported to be unstable in harsh conditions leading to a breakage of the multilayer chains. This would be evidenced by a decrease in redox-active quinones on the carbon surface, decreasing the electrochemical capacity seen in CV experiments (Figure ).
