Luminescence in copper-complexes is controlled by several photoinduced intra- and intermolecular processes, such as molecular flattening, intersystem crossing, solvation etc. For the elucidation of the underlying photophysics we employed femtosecond IR & UV/Vis transient absorption (TA) as well as transient anisotropy measurements and DFT calculations on a highly efficient luminescent heteroleptic mononuclear [1] copper(I)-complex. The results allow a rigorous comparison of the ultrafast dynamics in the UV/Vis spectral region with literature reports [2] [3] [4] on homoleptic copper(I)-complexes. Femtosecond IR TA facilitates an extended specification of the ultrafast processes in the heteroleptic mononuclear [1] copper(I)-complex.
