a Mechanism and synthesis of phase segregated healable metallosupramolecular polymers via assembly of 2,6-bis(1-methylbenzimidazolyl)pyridine (Mebip) ligands coordinated with Zn(NTf)2; b chemical structure and c schematic illustration of PDMS functionalized with 2,6-pyridinedicarboxamide ligands that coordinate to Fe(III) centers and the resulting Fe(III)–Npyridyl, Fe(III)–Namido and Fe(III)–Oamido coordination bonds. d Chemical structure and microphase-separated soft\hard two-phase polymer system with metal–ligand interactions as the dynamic motif
