X-ray study of a thermotropic biaxial nematic liquid crystal

Abstract

X-ray studies have been carried out on magnetically aligned samples of nematic bisrl-(p-n- decylbiphenyl)3-(p-ethoxyphenyl )propane-1.3-dionato] copper(I1). The diffraction pattern consists of three diffuse maxima as would be expected from an orthorhombic fluid. This provides further evidence in confirmation of the biaxiality of the nematic phase of this copper complex.
