An approach towards artificial quinone pools by use of photo- and redox-active dendritic molecules.
Molecules with one porphyrin and multiple quinone groups are described. The molecules are based on dendritic frameworks, with the quinone groups attached at the "internal" positions and the porphyrin attached at the focal point, leading to a characteristic layer architecture. When irradiated with visible light in the presence of 4-tert-butylthiophenol, the quinones were converted to quinols. Such a behavior mimics the function of quinone pools in photosynthesis.
