Abstract
Novel nonlinearly optically active compounds, well suited for electrooptical applications, have the following general formulae: ##STR1## wherein D is an electron donor group; A and A.sub.1, which may be identical or different, are each an electron acceptor group; and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each a lower alkyl radical or a hydrogen atom.
