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.

该合作项目的主要目标是设计卟啉-酞菁超分子阵列，可作为有效的人工光合系统的生物物理研究。为此，将使用通过轴向配位和主客体相互作用在超分子体系中特别组织的卟啉和酞菁单元的自组装。新型超分子配合物的结构对它们的电子物理性质的影响，特别是对激发能利用效率（吸收和电荷分离）和电荷分离态寿命的影响将被研究。这些知识将用于通过结构和络合变化优化特殊的光物理特性，从而开发新的光学材料，以有效地收集和转换太阳光。
