Photophysical investigations of novel porphyrin-phtalocyanine supramolecular assemblies with directional photoinduced electron and energy transfer

这个合作项目的主要目标是对设计的卟啉-酞菁超分子阵列进行光物理研究，这些超分子阵列可以作为高效的人工光合作用系统。为此，将使用超分子系统中通过轴向配位和主客体相互作用来特殊组织的卟啉和酞菁单元的自组装。研究了新型超分子络合物的结构对其光物理性质的影响，特别是对激发能量利用效率(吸收和电荷分离)和电荷分离态寿命的影响。这些知识将被用来通过结构和络合变化来优化特殊的光物理性质，从而允许开发新的光学材料来有效地收集和转换阳光。

The main goal of this collaborative project are photophysical investigations of designed porphyrin-phthalocyanine supramolecular arrays which can serve as efficient artificial photosynthetic systems. For this purpose specially organized self-assembling of porphyrin and phthalocyanine units by axial coordination and host-guest interactions in a supramolecular system will be used. The influence of the structure of the novel supramolecular complexes on their photophysical properties especially on efficacy of excitation energy utilization (absorption and charge separation) and charge-separated state lifetime will be investigated. This knowledge will be used for optimization of special photophysical properties through structural and complexation changes, allowing the development of new optical materials for efficient harvesting and conversion of sunlight.
