Synthesis of an Ionic Network by Molecular Recognition between Two Porphyrins at the Air-Water Interface
Abstract
The present work deals with the building of a planar ionic paving based on amphiphilic porphyrins. The engineering strategy is based on a molecular recognition at the air-water interface between two differently tetrasubstituted porphyrins P1 and P2. The direct mixing of MP1 and MP2 (M Cu, H2) leads to the spontaneous formation of face to face ionic heterodimers which have been fully characterized. On the contrary, when MP2 is replaced by its μ-oxo dimer (FeP2)2O, the steric hindrance prevents the heterodimerization with P1 and the final structure is now the claimed ionic planar network
