New protonic conductors instead of nafion film have been examined by using low molecular weight molecular complexes of 1) [Ni(dmit)_2] and 2) 2,2'-bi-1H-benzimidazole (H2BBIM) complexes. The crystal structures and ionic conductivities were evaluated in these complexes. M^+([18]crown-6)[Ni(dmit)_2]_2 complexes showed the ionic channel structure, which were designed by complex formation constants between the cations and 18-crown-6. The crystal (H3BBIM^+)(TCNQ)(Cl^-)_<0.5>(H_2O) showed high protonic conductivity, which were measured by the sandwiched electrode of nafion films. The protonic conductivity at room temperatur e was about 1.2 x 10^<-3> Scm^<-1>, which conductivity was observed at around 200 K. For the protonic conductivity, the hydrogen-bonding network structures were important in case of low molecular weight molecular complexes.

本文用低分子量的[Ni（dmit）_2]和2，2 ′-联-1H-苯并咪唑（H_2BBIM）配合物研究了取代Nafion膜的新型质子导体。在这些配合物的晶体结构和离子电导率进行了评价。M^+（[18]crown-6）[Ni（dmit）_2]_2配合物具有离子通道结构，该结构由阳离子与18-crown-6的配合物形成常数设计。晶体（H3 BBIM ^+）（TCNQ）（Cl^-）_<0.5>（H_2O）具有高的质子电导率，用Nafion膜夹层电极测量了其质子电导率。室温下的质子电导率约为1.2 × 10 ~（-1）<-3>S cm ~<-1>（-1），该电导率在200 K左右观察到。对于质子导电性，氢键网络结构在低分子量分子复合物的情况下是重要的。
