多相互作用的三（4-吡啶基）六氮杂菲那烯基阴离子（TPHAP−）的铵盐和钠盐（离子对）根据晶体结构显示出完全不同的离子导电性能。TPHAP柱状晶体显示出10−3 S cm−1的高电导率，即使在潮湿条件下也能保持其结构，而TPHAP二聚体晶体显示出10−5 S cm−1的电导率，但结晶度变差。由多重相互作用引起的主要单元结构实现了不同的水可及性，这解释了它们的离子电导率和对湿度的稳定性的差异。
Ammonium and sodium salts (ion pairs) of a multi-interactive tri(4-pyridyl)hexaazaphenalenyl anion (TPHAP−) showed completely different ion-conductive properties depending on the crystal structure. TPHAP columnar crystals showed a high conductivity of 10−3 S cm−1 while retaining their structures even under humid conditions, whereas TPHAP dimer crystals exhibited a conductivity of ∼10−5 S cm−1 with crystallinity deterioration. The main unit structures induced by multi-interactivity realized different water accessibility, which explains the differences in their ion conductivity and stability against humidity.
