Photosynthetic Antenna

Abstract The interior of chlorosomes, the main antenna system of the photosynthesizing bacterium Chloroßexus aurantiacus, is shown to contain no proteins in a fixed ratio to BChl c and in amounts that could be significant of direct chromophore-protein complexes. This excludes non-covalent chromophore-protein complexing -that has so far been found in all other antennae -as the main organizational principle of the interior architecture for chlorosom es of chlorophyll C. aurantiacus. Rather, these antennae constitute the first case of a chromophore-chromophore aggregate functioning as a photosynthetic light harvesting system.

Natural Photosynthesis

Natural photosynthesis inspired the scientific community to design and synthesize molecular assemblies that possess advanced light-harvesting and electron-transfer features. In this review, we present the preparation and the photophysical investigation of novel porphyrin–fullerene hybrids acting as artificial photosynthetic systems. Porphyrinoids stand as chlorophyll analogues and have emerged as suitable photosensitizers in supramolecular electron donor–acceptor hybrids. Fullerenes (C60) are versatile electron acceptors with small reorganization energy and low reduction potentials. The novel derivatives presented herein mimic the fundamental features of the photosynthetic reaction center, namely, light harvesting, charge separation, and charge transport. To this end, a comprehensive analysis on these key processes that occur in various porphyrin–fullerene entities is illustrated in this work.
