This supramolecular recognition element can be exploited to produce ordered arrays of interleaved porphyrins and fullerenes. C60⋅H2TpyP⋅Pb(NO3)2⋅1.5TCE (H2TpyP = tetra-4-pyridylporphyrin; TCE = 1,1,2,2-tetrachloroethane) crystallizes in the tetragonal P4/n space group and the structure has been solved to high resolution. The Pb2+ ions connect the pyridylporphyrins in infinite sheets with an interlayer spacing of 12.1 Å. The fullerenes are intercalated between these layers, acting as pillars. The 6:6 ring juncture bonds of C60 are centered over the porphyrins, bringing the layers into strict tetragonal register. This arranagement identifies the fullerene–porphyrin interaction as a structure-defining element. The same motif is seen in a related ribbon structure having C70 intercalated into HgI2-linked H2TpyTP. The supramolecular design principles involved in assembling these chromophores may have applications in materials science.Items in ResearchSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
