Abstract

A proton conductor includes a metal ion, an oxoanion, and a molecule capable of undergoing protonation or deprotonation, in which at least one of the oxoanion and the molecule capable of undergoing protonation or deprotonation coordinates to the metal ion to form a coordination polymer. The oxoanion is preferably a monomer. The oxoanion is exemplified by at least one selected from the group consisting of phosphate ion, hydrogenphosphate ion, and dihydrogenphosphate ion. The molecule capable of undergoing protonation or deprotonation is exemplified by at least one selected from the group consisting of imidazole, triazole, benzimidazole, benzotriazole, and derivatives thereof.

First claim

What is claimed is:

1. A proton conductor comprising:
a coordination polymer that is provided as a crystal structure having defined lattice parameters, the crystal structure having stoichiometrically:
a plurality of metal ions;
a plurality of oxoanions; and
a plurality of molecules capable of undergoing protonation or deprotonation,
the coordination polymer including a plurality of coordination entities that are repeatedly coordinated to bond the coordination entities with…
