Dicationic viologen species are known to form strong supramolecular complexes with cucurbituril, as well as participate in electron-transfer processes with donor systems. We describe the use of cucurbituril to modulate the electron transfer between a hybrid porphyrin (donor) and a viologen (acceptor) dyad. The X-ray crystal structure of these hybrids reveals the formation of 1D coordination polymers held together through zinc coordination in the solid state.
