用1，4-萘醌骨架修饰二硫纶镍配合物，合成了一种分子基质子和电子混合导体。复合物形成一个π堆积柱，两侧是无限的水分子氢键链。室温（RT）质子传导率为7.2 × 10（-7）S cm（-1），这是由质子通过水分子链连接到羰基氧上得到的。该化合物还显示出相对较高的RT电子电导率（4.1 × 10（-3）S cm（-1））和半导体行为（66 meV的小活化能），这源于中性自由基络合物组成的π堆积柱。
A molecule-based mixed conductor of proton and electron was synthesized by modifying a nickel(III) dithiolene complex with 1,4-naphthoquinone skeletons. The complex forms a pi-stacking column flanked by an infinite hydrogen-bonding chain of water molecules. Room-temperature (RT) proton conductivity was 7.2 x 10(-7) S cm(-1), which is derived from protons attached to carbonyl oxygens through the chain of water molecules. The compound also shows a relatively high RT electronic conductivity of 4.1 x 10(-3) S cm(-1) and semiconducting behavior with a small activation energy of 66 meV, which originates from the pi-stacking column composed of the neutral radical complexes.
