Koordinační sloučeniny push-pull chromoforů.

A literature search work concerning push-pull D- -A chromophores featuring intramolecular charge-transfer and coordination of the metal ions to the acceptor has been performed. Four push-pull chromophores based on 1H-imidazole-4,5-dicarbonitrile with modified length -conjugated bridge have been synthesized by cross-coupling reactions. Along with them, in the two other already prepared ligands have been used spectrophotometric titrations to determine the stability constants of Cu2+ complexes with investigated polarizable compounds.
