Several new chiral liquid crystal siloxane homopolymers and copolymers have been synthesized and studied as to their mesomorphic and ferroelectric behaviour. Almost all of them exhibit chiral smectic C phases over wide temperature ranges. DSC and X-r

L'etude du polymere (−Si(R)(Me)O−) n (R=(CH 2 ) n -O-Ph-O-CO-Ph-O-C m H 2m+1 ) montre que l'espaceur et le groupe terminal n'ont pas la meme influence sur le parametre d'ordre associe au groupe mesogene. Les variations apparentes du parametre d'o

Until recently no example was known with a miscibility gap separating two non-ordered mesophases (i.e.: nematic, smectic A or C) of the same symmetry. In most cases of binary solutions it was observed that either the phase diagram is of the simple eu

Parmi les differents motifs polyaromatiques mesogenes connus, seuls les derives hexasubstitues du benzene, du triphenylene, du truxene et de l’anthraqulnone presentent une (ou plusieurs) mesophase (s) colonnaire(s) D et/ou une phase nematique lenti

We know that the discovery of different mesomorphic compounds resulted from a rather empirical approach. It is an appealing task to look for previsional tools allowing to guide the synthesis of new mesomorphic series. For that purpose we used depolar

The X-ray diffraction patterns of powder samples of the fluid mesophase of the hexaalkoxybenzoates of triphenylene which is a disc-like molecule are similar to the diffraction patterns of non orientated nematic phase of rod-like molecules. Furthermor
