Copper(I)-complexes play a crucial role for the design of efficient and sustainable light emitters. To get a profound understanding of luminescence, controlled by photoinduced intra- and intermolecular processes, such as molecular flattening, intersystem crossing, solvation etc. we employed femtosecond UV/Vis transient absorption (TA) on mono[1]- and dinuclear[2][3][4] copper(I)-complexes. The results allow a rigorous comparison of the respective ultrafast dynamics in solution and solid phase, possibly controlled by metal-metal cooperativity. For the elucidation of molecular flattening we employed femtosecond mid-IR TA on a heteroleptic mononuclear copper(I)-complex.
