Preparation process of benzodifuranone dyes

The use of a multi-functional, chromophore containing, polymerizable compound for producing an optical element having non-linear optical properties (an NLO element) wherein the multi-functional chromophore is a compound capable of being polymerized into a cross-linked network and of being poled under the influence of an electric field whilst being polymerized into the cross-linked network, the compound having the generalized formula

Chromophore-containing compounds for opto-electronic applications

Amphiphilic compounds and oligomers and polymers derived therefrom suitable for Langmuir Blodgett deposition wherein the compounds have a polyamide backbone and hydrophobic groups pendant therefrom which pendant groups preferably contain chromophore groups. The compounds can be used to form non-centrosymmetric bilayers and are useful for forming various non-linear optical elements.

Amphiphilic compounds for sequential monolayer deposition

Metal values are extracted from aqueous solutions containing halide or pseudohalide anion using 1,1'-substituted 2,2'-biimidazole or bibenzimidazole compounds. Useful for the solvent extraction of zinc and copper from chloride leach solutions.

Process for the extraction of metal values and novel metal extractants

Process for the extraction of metal values with bisimidazole metal
