| Popis: | Recently, crystalline solid materials as proton conductors have attracted intensive attention. Herein, two highly stable complexes, 2D coordination polymer [Cd(3,5-DFPhH2IDC)2]·H2O (1) and supramolecule [Cd(3,5-DFPhH2IDC)2(phen)(H2O)]·0.5H2O (2) (phen = 1,10-phenanthroline), have been synthesized by using 2-(3,5-difluorophenyl)imidazole-4,5-dicarboxylic acid (3,5-DFPhH3IDC) as organic ligand. The water-assisted proton-conductive properties of 1 and 2 were investigated by impedance spectroscopy. Notably, the proton conductivity of both complexes attains the optimized value of 4.90 × 10−5 S cm−1 for 1 and 2.04 × 10−4 S cm−1 for 2 under 100 °C and 98% RH. Consequently, their proton-conducting mechanisms based on the Ea values were highlighted. |
