Syntheses and Physical Properties of Liquid Crystals Containing Ferrocene(XV) : Crystal Structure Analysis of [4-[ω-[4'-(4"-methoxyphenoxycarbonyl)phenoxycarbonyl]alkoxycarbonyl]phenyl]ferrocene by X-ray diffraction method.

Abstract

A series of monosubstituted ferrocene derivatives, [4-[ω-[4'-(4"-methoxyphenoxycarbonyl)phenoxycarbonyl]alkoxycarbonyl]phenyl]ferrocene (abbreviated hereafter MPAF-n. where n is a number of carbon atoms in methylene unit) were synthesized and studied on the liquid crystallinity of the compound in our laboratory. Only 4 kinds of MPAF-n showed the liquid crystallinity, where n=4, 6, 10 and 11, whereas 9 kinds of MPAF-n were synthesized. In this study, molecular and crystal structure of some of MPAF-n were determined by X-ray diffraction method. We will discuss the structure of liquid crystalline phase on the base of crystal structure.
