Abstract
- Abstract: The complex [Ir(azulene)(1,5-cyclocta-diene)]+ shows long-wavelength absorptions which are assigned to spin-allowed (λ max =536nm) and spin-forbidden (675nm) transitions. They are of mixed MLCT (Ir→azulene) and ILCT (azulene) character. At 77K the solid complex displays an emission (λ max =816nm) which originates from the MLCT/ILCT triplet. At r.t. in solution the complex undergoes a photosubstitution of the azulene ligand. It is suggested that in the CT state the azulene ligand looses its coordinating ability. [Copyright &y& Elsevier]
