TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The acid functionality is a carboxylic acid, thiocarboxylic acid, dithiocarboxylic acid, sulfonic acid, phosphonic acid, and/or boronic acid. The base is the hydroxide of an alkali metal or a tetraalkylammonium.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The method (M1) further involves providing a precursor CP as a suspension or solution in an organic solvent; and transforming the precursor CP suspension or solution to the ionic CP suspension or solution. The transforming involves hydrolysis of the ester with at least one equivalent of a base or involves hydrolysis of the acid ester and subsequently adding of at least one equivalent of base to yield a salt of the acid. The step of converting involves: reacting with an acid; or thermal degradation of the tetraalkylammonium; exchange of the alkali metal or tetraalkylammonium cations with a divalent or polyvalent cation; addition of a base; reaction with a nucleophile; and exchange of the metal salt from the bidentate or polydentate ligand to a second bidentate or polydentate ligand. The step of transforming involves: protonation by an acid; reaction with an electrophilic carbon, where electrophilic carbon is an alkylating agent; and reaction with a metal salt. The step of depositing involves printing or spraying an aqueous ionic CP solution. Preferred Components: The CP comprises repeating units having at least one side chain having an acid functionality and where the film dissolves in the presence of a base. The CP comprises repeating units having at least one side chain having a basic functionality and where the film dissolves in the presence of an acid. The precursor CP contains repeating units with at least one side chain comprising an amine, imine, phosphine or thioether. The precursor CP contains repeating units with at least one side chain comprising a bidentate or polydentate ligand. The precursor CP of the precursor CP suspension or solution comprises repeating units with at least one side chain that comprises an ester of carboxylic acid, thiocarboxylic acid, dithiocarboxylic acid, sulfonic acid, phosphonic acid, or boronic acid, where the ester is an alkyl substituted carboxylic acid ester.
