The invention provides novel non-polymeric and polymeric complexes and reaction products of lyotropic liquid crystal salts of aroyl acids which when anhydrous are excellent electrical conductors and superconductors of high critical temperature. The salts can be of various metals but especially of the alkali metals. The invention also provides reaction products of the complexes with copper metal, the products having excellent tarnish-resistant properties which make them suitable for protecting circuit boards and such from corrosion during storage. Copper/polymeric aroylacrylate salt reaction products when amorphous, especially when present in a thin film form, make superconductors of high critical temperature and current. Further, the invention provides a flexible process for converting various essential, water-bearing components of these complexes and reaction products into stable, anhydrous solutions well suited for applying to various substrates. A modification of the process provides products which can be used to coat substrates which wet poorly. Thin films of the alkali metal polymeric lyotropic liquid crystal salt complexes, because of their affinity for water, which is accompanied by a rapid, sensitive change in electrical resistance, make excellent hygrometric devices. They are especially well suited for monitoring processes which require that these complexes, reaction products, and complexation products be maintained in the anhydrous state, since the hygrometer sensor material's electrical response parallels that of the product being produced, rising to very high resistances as the anhydrous state is approached.
