A new Zr(IV)-based metal-organic framework, termed VNU-23 [Zr6O8(H2O)(8)(H2SNDC)(4)], where H2SNDC2- = 4,8-disulfonaphthalene-2,6-dicarboxylate, was synthesized. Subsequently, detailed structural analysis revealed that VNU-23 adopted the bcu topology with a structure characterized by densely packed sulfonic acid groups lining 6 angstrom channels. With this structural feature, an anchoring strategy was employed to dock the proton transfer agent, histamine, into the void space of VNU-23 to enhance the proton conductivity. Remarkably, the proton conductivity of this material reached 1.79 x 10(-2) S cm(-1) at 95 degrees C and 85% relative humidity without any appreciable loss of performance for at least 120 h.
