Control of interpenetration degree of the metal-organic frameworks (MOFs) can be a wise tactic to enhance their proton-conductivities. Two anionic MOFs, [(CH3)(2)NH2][In(L)]center dot 2.5DMF center dot 2H(2)O (FJU-16) and [(CH3)(2)NH2][In(L)]center dot 4.5DMF center dot 16H(2)O (FJU-17) (H4L= 4,4',4 '',4 ''-(1,4-phenylenbis(pyridine-4,2,6-triyl))-tetrabenzoic acid), with different degrees of interpenetration have been synthesized. The resulting 2-fold interpenetrated FJU-17 shows a higher intrinsic proton-conductivity (1.08 X 10(-2) S/cm, 100 degrees C) and wider performing temperature range (-40 to 100 degrees C) under the conditions of without additional humidity than the 4-fold interpenetrated FJU-16, owing to the more available void space and abundant guest molecules in FJU-17.
