A DNA nucleobase is polymerized by oxidative chemical vapor deposition and applied in electrocatalytic hydrogen evolution reaction. The unique synthesis enables the polymerization and protonation of guanine to emeraldine‐polyguanine (ePG), analog to polyaniline with four additional and potentially catalytic‐active amino functions enhancing the reactivity. Moreover, protons coserve as dopant and reactant in the catalytic electroreduction of protons to molecular hydrogen.
