Résumé
Dissym. functionalization of 5,5'-dimethyl-2,2'-bipyridine with a 'stilbene type' chromophore bearing a terminal alkoxy group leads to a new family of mesomorphic compds. exhibiting a rich thermotropic polymorphism. A succession of smectic B, smectic A and nematic phases was obsd. For the octyloxy compd., an addnl. phase was detected which was hexatic in symmetry. [on SciFinder(R)]
