The Synthesis and Characterization of Some Perylene and Anthraquinoic Dichroic Dyes for Liquid Crysalkylperylene -3,4,9,10 — diimides, order parameters in the commercially available liquid crystal mixture E7, ranging from 0.723 to 0.745 (corresponding to dichroic ratios of 8.7 to 13.8) were obtained. The dichroic ratio was obtained by measuring the polarized absorption spectra in both the paralle

Some New Thermotropic Discogens,fied by the miscibility method. The rufigallol hexa-n-nonanoate exhibits a stable D. columnar discophase. Some chemical possibilities for new side chains are explored. The hexa-p-n-heptyloxycinnamoyloxytriphenylene exhibits a fluid discophase stable from 146.7 to 242°C. The discogenic potentialities

,Characterization of Two Isomeric Cyano-Ester Homologous Series — I,e paired in the nematic phase as a basis for the occurence of reentrant phenomenon. In this study we sought to prepare materials in which the dipolar forces within the constituent molecules could be altered and hence, the degree of pairing in the nematic phase could be changed. Thus, a comparison of

,Effect Of Molecular Structure Of Rigid — Flexible Polyesters on their Thermotropic Liquid Crystallitheoretical point of view. As early as in 1941, Kargin and Slonimski (1) predicted that the backbone polymers should exhibit the liquid crystalline properties. Taking into account the fact that almost all of the low molecular weight liquid crystals known so far consisted of rigid polarizable molecul

Relationships Between Molecular Structure and the Incidence of Crystal B and Hexatic B Phases,s have short-range in-plane positional ordering, and long-range bond orientational order, both within and between the layers (hexatic B). The other phase, however, shows three dimensional crystalline order (crystal B). The structure adopted by the B phase (either hexatic or crystal) is dependent on
