A novel supramolecular electron donor-acceptor hybrid (2.1) and an electron donor-acceptor conjugate (3), both exhibiting a remarkably shifted Q band in the NIR region of the solar spectrum, were prepared. Irradiation of the supramolecular ensemble 2.1 within the visible range leads to a nanosecond lived radical-ion pair state Zn-azulenocyanine(center dot+)-C-60(center dot-).
