Abstract
A chiral center can be introduced in the lateral substituent of mesogens co ntaining four rings in the main core. The racemic compounds present a conse quent nematic range. Comparison with compounds having a linear chain indica tes that the bifurcated character of the chain does not affect drastically the nematic range, Bulky substituents like aromatic fragments can be also i ntroduced on the chiral center. Preliminary results on the properties of on e optically enriched compound are presented.
