One approach to mimic the photosynthetic energy conversion system in nature is the use of complex synthetic molecular arrays containing chromophores, electron donor and electron acceptor linked by covalent and non covalent bonds. The energy stored in these systems as a external circuit in a suitable photoelectochemical cell. In this work an electron donor-acceptor porphyrin dyad (ZnP-P) was synthesized by linking an electron acceptor porphyrin; 5,15-bis(4-carboxyphenyl)-10,20-bis(4-nitrophenyl)porphyrin (P), and electron donor porphyrin; Zn(II)5-(4-aminophenyl)-10,15,20-tris(4-methoxylphenyl) porphyrin (ZnP) by amide bond.
