To seek new types of proton conductive materials, we have successfully synthesized three novel hydrogen-bonded supramolecular complexes, [M(m-FPhH2IDC)2(H2O)2]·4H2O (M = Cd (1); Co (2)) (m-FPhH3IDC = 2-(m-fluoro)phenyl-4,5-imidazole dicarboxylic acid), and [Mn(m-FPhH2IDC)2(2,2′-bipy)]·H2O (3) (2,2′-bipy = 2,2′-bipyridine) under hydro(solvo)thermal conditions. After analyzing crystal structures and
为了寻求新型的质子导电材料,我们已经成功地合成了三种新型的氢键超分子配合物[M(m -FPhH 2 IDC)2(H 2 O)2 ]·4H 2 O(M = Cd(1);)。 Co(2))(m -FPhH 3 IDC = 2-(m-氟)苯基-4,5-咪唑二羧酸)和[Mn(m -FPhH 2 IDC)2(2,2'-bipy)] ·水2 O(3)(2,2'-bipy = 2,2'-bipyridine)在水(溶剂)热条件下。分析晶体结构和验证的热,水和化学稳定性后1 - 3,的质子传导率1 - 3中的水蒸汽已被测定,结果表明,它们的质子电导率随着温度和相对湿度(RH)相应增加。在98%RH和100℃,的质子传导率1 - 3达到2.77×10的最高值-4,3.42×10 -5和4.61×10 -5 小号厘米-1, 分别。通过PXRD确定和活化能计算的质子转移机制,1 - 3已经被提出。我们的研究表明
