论文摘要
已合成了沿Nanoring轴螺纹的Cy7氰糖染料（己氨酸indotrcricarbocyanine）的纳米型 - 对烷烷超分子组件，已被合成，作为光收集复合物LH1和紫色细菌照片中的光收集复合物LH1和紫色反应中心之间的能量转移的模型。该复合物显示有效的能量转移从中央氰染料到周围锌卟啉纳米氧化锌。我们提出了一个理论模型，该模型重现了纳米元的吸收光谱，并量化了Nanoring和中央染料之间的激子耦合，从而解释了有效的能量传递，并阐明了与结构相关的自然光收获系统的相似性。
A nanoring-rotaxane supramolecular assembly, with a Cy7 cyanine dye (hexamethylindotricarbocyanine) threaded along the axis of the nanoring, has been synthesized as a model for the energy transfer between the light harvesting complex LH1 and the reaction center in purple bacteria photosynthesis. The complex displays efficient energy transfer from the central cyanine dye to the surrounding zinc porphyrin nanoring. We present a theoretical model that reproduces the absorption spectrum of the nanoring and quantifies the excitonic coupling between the nanoring and the central dye, explaining the efficient energy transfer and elucidating the similarity with structurally related natural light harvesting systems.
