Self-assembly of a bis-porphyrinic supramolecular rectangle using two orthogonal binding strategies.

A bis-porphyrinic rectangle is created via a double self-assembly algorithm using two orthogonal coordination themes, i.e. first a 90 degrees building block composed of a dynamic heteroleptic Cu(I) or Ag(I) bisphenanthroline followed by a coordinative dimerization using the pyridine-zinc porphyrin motif; the spectroscopic and electrochemical properties as well as the dynamic nature of the supramolecule were tested.
