Automated Investigation of Metal-ligand Interactions by a Newly Established Robotic Workflow for Titrations.

Abstract

In this work, we present a new workflow to set up an automated platform for the investigation of metal complex formation in solutions. With the utilization of this robot titration platform, the generation of an abundancy of solvated metal complexes in differing coordination number is possible in a simple manner. The generated complexes can subsequently be sampled into differing vessels to examine them in detail. We present sampling for UV/Vis and NMR spectroscopy at chosen model systems, however, the platform can easily be adapted to provide samples for other techniques, e.g., for infrared spectroscopy.
