Non-linear optic process using N-(4-nitrophenyl)-2-(hydroxymethyl)-pyrrolidine and deuterated derivatives thereof

摘要

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): <IMAGE> (I) 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.
