Electron-transfer induced mesomorphism in the ferrocene-ferrocenium redox system: first ferrocenium-containing thermotropic liquid crystal

Chem. oxidn. (Ag tosylate, acetone, room temp.) of a nonmesomorphic persubstituted ferrocene deriv. leads to the corresponding ferrocenium species which exhibits a smectic A phase (polarized optical microscopy, DSC, x-ray diffraction). [on SciFinder(R)]
