当标题化合物以固体微粒的形式溶解在硝基苯液滴阵列中或当电极浸入固体的三维水性悬浮液中时，当其固定在电极表面上时，检查标题化合物的水性两相伏安法。在每种情况下，观察到发生不同的电极反应，即使支持电解质没有改变，也有反离子穿过液体转移，|液体界面，或固体颗粒的电化学溶解，或嵌入固体晶体内的各个氧化还原中心之间的建议扩散型电子跳跃。
The aqueous biphasic voltammetry of the title compound is examined when it is immobilised on an electrode surface either when dissolved in an array of nitrobenzene droplets, in the form of solid microparticles, or when an electrode is immersed into a three‐dimensional aqueous suspension of the solid. In each case, a different electrode reaction is observed to occur, even though the supporting electrolyte is unchanged, with either counter ion transfer across a liquid | liquid interface, or with electrochemical dissolution of the solid particles, or a suggested diffusive‐type electron hopping between individual redox centres embedded within the solid crystals.
