| Abstract: | For the benzoquinone/porphyrin/benzoquinone sandwich-molecule 1 a highly symmetrical structure with parallel ring planes and interplanar distances of 342 pm was derived from X-ray analysis. 1 shows, in comparison to 2, a very strong quenching of fluorescence indicating intramolecular electron transfer. |
