Abstract: High Resolution Image Download MS PowerPoint Slide We report enhanced proton conductivity promoted by a structural phase transition of MFM-504(Cu)-DMF to MFM-504(Cu)-MeOH and to MFM-504(Cu)-OH via ligand substitution upon exposure to MeOH and H 2 O vapors, respectively. MFM-504(Cu)-DMF can be synthesized by the solvothermal reaction of Cu(NO 3 ) 2 ·3H 2 O and the flexible zwitterionic ligand, imidazolium-1,3-bis(methylenedicarboxylate) (imidc – ), to afford a unique layered interwoven network structure. MFM-504(Cu)-OH shows a proton conductivity of 5.01 × 10 –4 S cm –1 at 80 °C and 99% relative humidity (RH) with an activation energy ( E a ) of 0.80 eV, indicating a vehicle mechanism within MFM-504(Cu)-OH.
