The trimeric perfluoro-ortho-phenylene mercury compound Hg3 and Hexa-alky substituted derivatives of Hexa-<i>peri-</i>hexabenzocoronene (HBC) show unique supramolecular interactions in solution and the solid-state. The addition of Hg3 to HBC solution leads to a noticeable red-shifting of the maximum absorbance of the HBC chromophore and a dramatic decrease in HBC luminescence as well as an appearance of phosphorescence from the Hg triad (c.a. 577 and 625 nm), which is consistent with the formation of aggregates. Transient absorption spectroscopy of the HBC: Hg3 aggregates in chlorobenzene solution reveals the triplet is localized on the HBC chromophore. A confocal laser scanning microscope is used to further characterize the surface of the HBC/Hg3 complexes.
