Ultrafast studies on luminescent mono- and dinuclear copper(I)-complexes in solid and liquid phase — •Merten Grupe1, Florian Bäppler1, Fabian Dietrich2, Daniel Volz3, Stefan Bräse4, Rolf Diller1, and Markus Gerhards21Dept. of Physics, TU Kaiserslautern, 67663 Kaiserslautern — 2Dept. of Chem., TU Kaiserslautern, 67663 Kaiserslautern — 3Cynora GmbH, 76646 Bruchsal — 4Dept. of Org. Chem., KIT, 76131 Karlsruhe

The efficiency of 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 UV/Vis transient absorption (TA) as well as transient reflectivity (TR) spectroscopy and DFT calculations on luminescent mono-[1] and dinuclear[2] 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. Together with the investigations of [3] fundamental kinetics of homo- and heteroleptic mononuclear copper(I)-complexes can be contrasted.
