Supramolecular Stacks of Bis(imidazolyl)porphyrin through Metal Coordination

More Information
Summary:cis- and trans-bis(1-methyl-2-imidazolyl)tetraethyltetramethylporphyrin Mg complexes were prepared. 1H NMR, absorption, and fluorescence spectra suggest that Mg has a high tendency toward dimer formation through coordination from imidazolyl to metal in a similar way to Zn, and accepts further the sixth coordination, which never occurred in Zn complexes. Propagation of the organization from a dimer to a trimer for trans-Mg complex starts at such a low concentration level as 10−5 M (1 M = 1 mol dm−3) and a 2 × 10−3 M solution organized the system to a 2.34 mer on average.
