Cryatalline channels in coordination polymer and metal-organic framework are available to enhance the dynamics of accommodated ions. We have worked on the synthesis of solid-state anhydrous (water-free) proton conductors with coordination polymers. [Al(14ndc)(OH)] (14ndc = 1,4-naphthalenedicarboxyalate) possessing straight 1-D channels can densely involve protic molecules (imidazole or histamine) and the obtained composites show high anhydrous proton conductivity (above 10-3 Scm-1 at 150 �C). We also fabricated crystalline phosphate 1-D coordination polymer with rotatable imidazolium cation [Zn(HPO4)(H2PO4)2](ImH2)2. This also shows 10-3 Scm-1of conductivity and the fabricated membrane electrode assembly gives a stable open circuit voltage (~0.8 V) at 120 �C. It evidences the compound works as electrolyte of fuel cell under anhydrous condition.RefererencesNat. Mater. 2009 , 8, 831-836.Nat. Chem. 2009 , 1, 695-704.Angew. Chem. Int.
