Photochemistry of Dithiocarbamate Cu(SCNEt) Complex in CHCl. Transient Species and TD-DFT Calculations.

Nanosecond laser flash photolysis was used to study the mechanism of photochemical transformations of the diethyldithiocarbamate Cu(II) complex (Cu(dtc), where dtc ≡ SCNEt anion) in chloroform solutions. The electron transfer from the excited Cu(dtc) complex to a solvent molecule leads to the appearance of the primary intermediate, the [ClCu(dtc)(dtcCHCl)] complex, where a dtcCHCl molecule is coordinated with a copper ion via one sulfur atom. In the fast reaction (k = 2.

Femtosecond spectroscopy of the dithiolate Cu(II) and Ni(II) complexes.

Femtosecond spectroscopy was applied to study the ultrafast dynamics for the excited states of dithiolate Cu(ii) and Ni(ii) complexes. The detailed information on the initial steps after the absorption of a photon by the metal complexes is of fundamental importance to understand the mechanism of photochemical reactions. The fast processes for the dithiolate complexes have hardly been studied.
