Donor‐Acceptor Hybrids for Organic Electronics

This review deals with functional molecules able to transfer one electron from the donor to the acceptor moiety upon light irradiation. Donor‐bridge‐acceptor molecular systems are of interest for a wide variety of applications, namely artificial photosynthetic architectures and materials for organic photovoltaic devices. In the respective sections, we have addressed some of the most recent and remarkable examples to explain the construction of artificial photosynthetic systems by means of a variety of remarkable photo‐ and electro‐active electron donor molecules covalently or supramolecularly connected to a fullerene unit as the electron acceptor unit. We have also systematically reviewed the most efficient fullerene derivatives used for photovoltaic applications by blending with different semiconducting organic polymers or small molecules, affording all‐organic solar cells.
