Tricyclic spacer systems for nonlinear optical devices

NLO chromophores of the form of Formula (I): and the acceptable salts, solvates and hydrates thereof, wherein Z, X, &#x3c0;, D, A and R have the definitions provided herein. 

Heterocyclical anti-aromatic chromophore architectures

NLO chromophores of the following general formula: wherein each R represents a spacer system or substituent moiety as disclosed herein.

Heterocyclical, substituted phenazinamine-type non-linear optic chromophore architectures

The present invention relates to electroactive compounds capable of undergoing a change in light absorption and refraction due to an applied electric field and a permanent change in refraction due to exposure to predetermined bands of optical radiation. The present invention also relates to electroactive compositions containing such electroactive compounds, electrooptical components comprised of such electroactive compositions and electrooptical devices comprised of such electrooptical components, as well as novel processes of making the same.

Electroactive compounds, compositions and devices and methods of making

The production of 3-cyano-3,5,5-trialkylcyclohexanone from the reaction of 3,5,5-trialkylcyclohexenone and hydrocyanide at elevated temperature and in the presence of a catalytic amount of an onium cyanide, is disclosed herein.

Catalyst and process for the production of

Diphenyl ethers of the formula ##STR1## wherein m is 1-3, n is 1 or 2, R is hydrogen, carboxy, carboxylate salt or ester, formyl oxime, cyano, alkyl, alkoxy, chloro, bromo, or N, N-dialkyl amino, are prepared by reacting a chloro-fluoro-benzotrifluoride of the formula ##STR2## wherein m and n are as defined above with a nitro-phenoxide of the formula ##STR3## where R is defined above, and M is a cation of an alkali metal or an alkaline earth metal.
