Abstract
5,5'-ethylenebis(octaethylporphyrin) 1 and its metallocomplexes with v arious combination of metals (Zn, Cu, and Ni) 2-10 were prepared. On t he basis of H-1 and C-13 NMR as well as MCD spectra, it was concluded that interactions between the two intramolecular porphyrins become att ractive when at least one of the two rings is converted to zinc porphy rin. The phenomenon was explained by dipole-dipole interaction arising from the large polarization in Zn complexes.
