Our past activities in this field have led to dually emissive platinum complexes with sigma bonded coumarin, thioxanthone and BODIPY ligands, which show efficient fluorescence and phosphorescence emissions from the platinum-bonded dye ligands with unprecedented phosphorescenec quantum yields. We now strive to carry on these activities with the following aims: i) Further boosting the quantum yields of long-lived phosphorescence emission and shifting the emission to lower energy, into the red of the visible and into the near infrared. This spectral region is of particular relevance for applications in biology and medicine; ii) Developing of highly efficient panchromatically absorbing photocatalysts and photosensitizers with two different dye ligands. We further aim at broadening the scope of utilization of our complexes as sensitizers and photocatalysts and to probe at least exemplarily the potential of our target complexes in biology. Those tests will be performed in the laboratories of Marcel Leist at the Biology Department of our faculty.
