Liquid Crystals IV. Electro-Optic Effects in p-Alkoxybenzylidene-p’-Aminoalkylphenones and Related Compounds

A systematic study of the relationship between molecular structure and the electrical properties of liquid crystals has recently led us to the discovery of several new electro-optic effects in nematic2,3 and cholesteric-nematic4,5 materials. In the present work, which is a continuation of this study, a series of compounds with both nematic and smectic behavior were examined under externally applied electric fields. These new compounds were derived from p-alkoxybenzylidene-p’-aminoalkylphenones (I) and were prepared by conventional procedures.
