Further transformation of the iodo groups by a Pd-catalyzed reaction allowed easy preparation of further extended p-conjugated carboxyZnPcs. These dyes have been used as sensitizers in dye-sensitized solar cells, which exhibit a panchromatic response and moderate overall efficiencies.bisthiophenedye-sensitized solar cellsnear-infrared dyesphthalocyaninesNanocrystalline Tio2 FilmsPhotovoltaic CellsRedox ElectrolyteEfficiencyPorphyrinsConversionSystemConvergent Synthesis of Near-Infrared Absorbing, "Push-Pull", Bisthiophene-Substituted, Zinc(II) Phthalocyanines and their Application in Dye-Sensitized Solar Cellstext::journal::journal article::research article
