Research Abstract

Using Dawson-type POMs, which are redox-active and can be organically derivatized, hybrid POM ligands with N3 coordination sites were synthesized. Two linking methods, one through pi-conjugated ligands, the other through non-conjugated linkers, were used to connect the POM and organic ligand groups. The reaction of the obtained hybrid POM ligands and iron sources gave bis-POM-capped mononuclear iron complexes.
There were clear differences between the conjugated and non-conjugated systems.
The Fe-ligand MLCT bands appeared at very different wavelengths, due to the contrasting electron withdrawing effects of the POM unit in the two systems.
