摘要：

(Figure Presented) Playing the field: Application of an electric field to the thermodynamic equilibria of constitutionally dynamic sets of imines and amines that contain an imine with liquid-crystalline properties and a negative dielectric anisotropy leads to the amplification of the constituent that couples most strongly to the electric field, namely the liquid crystal (LC, see example). The field can thus induce a liquid to nematic phase transition. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
