Synthesis and Physical Properties of Liquid Crystals Containing Ferrocene ( XXVI ) Liquid Crystalline Phase Transition of 1,3-Disubstituted Ferrocene Derivatives

Abstract

In this study, 1,3-disubstituted ferrocene derivatives, 1,3-bis[ω-[4-(4-methoxyphenoxycarbonyl)phenoxy]alkyloxycarbonyl]ferrocene, were prepared. The phase transition behavior of these compounds are compared with that of 1,1 '-disubstitution ferrocene derivatives including the same substituent. The result obtained here is discussed from a viewpoint of liquid crystallinity influence by the positions introduced the substituents.
