Abstract
Novel nematic liquid crystalline azo-compounds have been found, which are anisotropic over a wide temperature range which includes room temperature. The compounds are temperature, light and moisture proof. They exhibit no dynamic scattering. The compounds may be employed in E.S.R. and N.M.R. spectroscopy, and, as the case may be mixed with other nematic liquid crystalline compounds, in displays.
