ABSTRACT:
The invention relates to novel paranitroaniline derivatives usable in non-linear optics and electrooptics, as well as to the preparation process for the same. These derivatives are in accordance with formula (I): ##STR1## in which one or more of the hydrogen atoms are optionally replaced by deuterium atoms. They are prepared by reacting one of the two pure optical isomers of 2-(hydroxymethyl)-pyrrolidine with a parahalogenonitrobenzene.
The optically pure derivatives can be used in optical or optoelectronic devices.
