Femtosecond dynamics in nanostructured organic complexes (B09)

有组织的有机和金属/有机配合物表面的能量和电荷转移过程的动力学对它们的功能是重要的。这些电子特性通过飞秒激发和时间分辨双光子光电发射进行了研究。相对于底物能带的单重态和三重态能级位置，导致三重态的自旋改变现象，分子间的竞争以及吸附物与底物的相互作用是主要的研究课题。在空间约束系统中，期望有不同的电子动力学。能量和电荷的转移速率来源于表面活性物质的受控稀释。

The dynamics of energy and charge transfer processes in organized organic and metal/organic complexes on surfaces are important for their functions. These electronic properties are investigated by femtosecond excitation and temporally resolved two-photon photoemission. Singlet and triplet energy level positions relative to substrate bands, spin-changing phenomena leading to triplet states, and the competition between intermolecular and adsorbate-substrate interactions are central research topics. In spatially constraint systems different electronic dynamics are expected. Energy and charge transfer rates are derived from a controlled dilution of the active species on the surface.
