Abstract

Procedimiento de obtención de cristales líquidos colestéricos por recristalización estereoselectiva. Procedimiento mediante el cual se sintetiza los polímeros, el PTOBEE (C{sub,26 H{sub,20 O{sub,8 ){sub,n y el PTOBDME (C{sub,34 H{sub,36 O{sub,8 ){sub,n , con la adición de dicloruro de ácido y DL-treo-1,2-butanodiol en Cl-naftaleno y DL-1,2-dodecandiol con óxido de difenilo, respectivamente, pasándolos por una corriente de nitrógeno a temperatura ambiente, calentando la mezcla, decantando en tolueno la mezcla y filtrando. En el tolueno resultante de decantar el polímero precipita el enantiómero (-)PTOBEE. Los compuestos obtenidos tienen naturaleza de cristal líquido colestérico, obtenidos por recristalización estereoselectiva en tolueno.
