Abstract

New multifunctional ligands based on the combination of 4H-imidazoles with pyridine subunits have been synthesised. The long wavelength absorptions originating fromthe merocyanine-chromophore can be shifted towards the near infrared (NIR) region by introduction of additionalauxochromic groups. Due to different complexation spheres these hybrid-ligands form the requirements for the construction of heterobimetallic complexes. In addition, the hybrid ligands are redox active compounds showing two separated fully reversible reductions. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
