合成了具有四面体构型的四阳离子化合物。四个阳离子单元被引入到一个季碳通过-CH2-间隔物上。尽管核心周围存在空间拥挤，但铜(I)催化的叠氮-炔环加成反应的高活性以及三氮唑单元的季胺化使这种分子设计成为可能。乙二醇尾四阳离子是离子液体，在25℃时具有10(-6)S厘米(-1)数量级的离子电导率。
Tetra-cationic compounds with tetrahedral geometry were synthesized. Four cationic units were introduced on a quaternary carbon through -CH2- spacer. Despite of steric crowding around the core, high reactivity of Cu(I)-catalyzed azide-alkyne cyclo-addition reaction followed by quaternization of the triazole unit enabled this molecular design. Tetra-cations with ethylene glycol tails were ionic liquids with 10(-6)S cm(-1) order ionic conductivity at 25 degrees C.
