Platinum Complexes with Sigma bonded BODIPY, Aza-BODIPYS and Squaraines as Dual Emitters and photocatalysts

我们过去在这一领域的活动已经导致了双发射铂配合物与σ键合香豆素，噻吨酮和BODIPY配体，这表明有效的荧光和磷光发射的铂键合染料配体与前所未有的磷光量子产率。我们现在努力开展这些活动，目标如下：i）进一步提高长寿命磷光发射的量子产率，并将发射转移到较低能量，进入可见光的红色和近红外。该光谱区域在生物学和医学中的应用是特别相关的; ii）开发具有两种不同染料配体的高效全色吸收光催化剂和光敏剂。我们进一步的目标是扩大我们的配合物作为敏化剂和光催化剂的利用范围，并至少示范性地探测我们的目标配合物在生物学中的潜力。这些测试将在我们学院生物系的Marcel莱斯特实验室进行。

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.
