Charged Porphyrins: π-Electronic Systems That Form Ion-Pairing Assembled Structures

Noncovalent interactions are important for determining the assembling modes of materials. Electronically neutral π-systems form stacking structures based on π–π interactions, which mainly derived from dispersion forces. Introducing charges into would affect interaction, owing to increased contribution electrostatic This unique we have proposed as iπ–iπ can provide ion pairs that assembled structures. The number possible combinations be obtained product components being paired. As π-electronic ions, especially anions, more reactive than electronically π-systems, their stabilization is required. We recently focused porphyrins platforms stabilize ions by charge delocalization over large π-systems. In addition, facile structural modifications enable tuning assembly and functionalization ion-pairing assemblies. this account, progress charged porphyrin derivatives behaviors summarized. π-Electronic exhibit distinct depending nonconventional between systems. adopted assemblies because diversity states. account focuses
