Abstract
In one embodiment this invention provides a novel class of azomethine compounds which exhibit nonlinear optical response, such as 4-(4-dimethylaminobenzylideneamino)-4'-nitrostilbene: ##STR1##
Claims2
In a light switch or light modulator device with an organic nonlinear optical component, the improvement which comprises said optical component consisting of a transparent solid medium which is a blend of constituents comprising (1) a host thermoplastic polymer;
- and (2) a guest organic compound exhibiting nonlinear optical response which corresponds to the formula:
- ##STR25## where X.sup.1 is --NR.sup.2 R.sup.2, --OR.sup.2 or --SR.sup.2 ;
- R.sup.1 is hydrogen or methyl;
- R.sup.2 is hydrogen or a C.sub.1 -C.sub.20 alkyl group;
- and Z.sup.1 is --NO.sub.2, --CN or --CF.sub.3.
