New binuclear nickel(II) phthalonitrile complexes, viz., NiII 2,2′,9(10),9′(10′),17(18),17′(18′),24(25), 24′(25′)-tetra(phenylene-1,2-dioxy)bisphthalocyanine and Ni II 2,2′,9(10),9′(10′),17(18),17′(18′), 24(25),24′(25′)-tetra(4-tert-butyl-phenylene-1,2-dioxy) bisphthalocyanine, were synthesized. The complexes were characterized by electronic spectroscopy and MALDI-TOF mass spectrometry and studied as active components for membranes of ion-selective electrodes in solutions of dicarboxylic acids.
Ortho-bis(etherdianhydrides)
-
, (2008/06/13)
Disclosed herein are novel poly(imide-ethers) containing ortho substitution in the main chain of the polymer. These polymers are made from novel aromatic bis-carboxylic anhydrides which contain two ether groups attached to an aromatic ring in ortho positions to each other. The polymers are particularly useful for films, fibers and encapsulation, as well as thermoplastics.

Binuclear phthalocyanines in which the two phthalocyanine nuclei are covalently linked through four-atom bridges, derived from catechol, have been prepared and characterized.Metal-free 2,9,16,23-tetra-(3,3-dimethylbutyl)phthalocyanine and 2,9,16,23-tetra-(2-trimethylsilylethyl)phthalocyanine were prepared as examples of non-oxygenated mononuclear phthalocyanines soluble in organic solvents.Catalytic hydrogenation of 1,2-bis-(3,4-dicyanophenyl)ethyne and 1,4-bis-(3,4-dicyanophenyl)buta-1,3-diyne gave 1,2-bis-(3,4-dicyanophenyl)ethane and 1,4-bis-(3,4-dicyanophenyl)butane respectively.From these precursors, metal-free phthalocyanine dimers containing ethylene and tetramethylene bridges, joining the phthalocyanine nuclei, were prepared.Two of the two-atom bridge phthalocyanine dimers represent the first characterized phthalocyanine dimers not containing alkoxy or oxygenated groups.
