A recently discovered method for selective activation of the B–H bonds in closo-borates towards nucleophilic substitution through aryliodonium zwitterions[1] has opened up a convenient access to a large variety of polar and ionic self-organizing materials.[2] Such zwitterions are easily obtained from closo-borates and ArI(OAc)2 and undergo facile reactions with nucleophiles according to the 10-I-3 or 9-I-2 mechanism. Appropriate derivatization of the resulting functionalized closo-borates leads to polar or ionic liquid crystals. The former are pyridinium, sulfonium, or quinuclidinium zwitterionic derivatives I and II, and are of interest as high dielectric anisotropy (Δε) additives to materials for LCD applications.[3] Ionic liquid crystals (ILC) are being developed as anisotropic ion conductors (electrolytes) for battery applications.
