The design of donor-acceptor systems and the study of their photo-induced electron transfer processes are of current interest in artificial photosynthesis and solar energy conversion. Among donor-acceptor conjugates, systems with defined intramolecular distances and orientations are of particular importance to manipulate the efficiency of the electron transfer processes. These newly synthesized compounds were fully characterized using 1H NMR, UV-Vis, electrochemical and mass spectrometric methods. Evidence for interaction in the ground state systems was obtained from spectroscopic and computational studies. Electron transfer from the excited znic porphyrin to fullerene was reveled by steady and time-resolved emission studies.
