Abstract
High Resolution Image Download MS PowerPoint Slide Developing biomimetic systems to simulate photosynthesis in purple bacteria has attracted considerable attention. Nevertheless, studies have been concentrated on mimicking light harvesting while integrating light harvesting with other necessary photosynthetic steps (i.e., charge separation or photochemical reaction) have been explored relatively less. A feasible approach is to construct antenna–reaction center complexes by learning the structure and function of the LH1–RC complex in purple bacteria. Hence, in this review, we have first summarized strategies employed in the rational construction of ring-like arrays mimicking LH1 or LH2 and biomimetic reaction center (RC) complexes derived from porphyrin, emphasizing functional properties. Depending on the type of RC model, it can be coupled with a suitable light-harvesting antenna to realize efficient light harvesting, charge separation, and photocatalyzed CO 2 reduction, thus simulating multiple photosynthesis steps in purple bacteria. On this basis, we anticipate that this review would provide inspiration for scientists and further stimulate future studies in this area. We have summarized issues to be tackled and uncharted territories in biomimetic photosynthetic study.
