US 5,443,753 A · Reaction products of lyotropic liquid crystal salt complexes

Abstract

The invention provides novel polymeric and non-polymeric, liquid crystal type, chemical salt complexes of aroyl acids and monovalent and polyvalent metals. They are formed by covalent and coordinate bonding for use as electrical superconductors, as electrolytes in alkali metal batteries, electrochromic windows, static dissipative polymers, etc. The invention also provides processes for manufacturing such complexes, including the in situ formation in and on various metals and oxides. The processes also include the use of supercritical solvents such as carbon dioxide to solubilize the complexes for introduction into plastics and inorganic superconductors. The chemical complexes include the triads formed of liquid crystal aroyl salts, non-polymeric ligand solvents, and polymeric aroylacrylate salts. Both homopolymer and copolymer complexes of the metal aroylacrylates may be prepared and the latter may be cross-linked. Novel covalent, liquid crystal, reaction product complexes of lyotropic liquid crystal, metal aroylacrylate complexes and isocyanates (both polymeric and non-polymeric) are prepared. These are dyes having a high degree of conjugated unsaturation. Solutions of the reaction products of monovalent and polyvalent metal complexes can be prepared. Excess ligand solvents used in preparing these materials can be vaporized in a controlled way to produce liquid crystal systems. These systems can be cross-linked. Supercritical fluids such as carbon dioxide can be used to dissolve these various complexes and allow their distribution into both plastic particles and powdered inorganic superconductors so as to distribute complexes uniformly throughout the particles so as to enhance properties such as electrical conductivity when the particles are formed into larger systems.
