Description
Summary:The photochemistry of the [Ir III Cl 6 ] 3– complex in aqueous solutions is studied by the methods of stationary and laser flash photolysis. As a result the of absorption of a light quantum, parallel processes of photoaquation and photoionization occur. The aquated electron , which is formed with a quantum yield of 0.12 (excitation at 266 nm), is predominantly decayed in reactions with the initial complex and dissolved oxygen. The rate constant of the capture by the [Ir III Cl 6 ] 3– complex is measured. The main final photolysis products are Ir(III) complexes with different compositions of ligands and several percent of Ir(IV) complexes. The final products are formed in the time range from milliseconds to seconds.
