    Polymer topology-controlled self-healing properties of polyelectrolyte hydrogels based on DABCO-containing aromatic ionenes

    DABCO-containing polymers based on a disubstituted phenylene dibenzamide core constitute versatile gelators enabling the formation of hydrogels for different applications. In this work we have found that the polymer topology, controlled by the disubstitution pattern of the aromatic core, plays a crucial role on the self-healing properties of the corresponding hydrogels. Specifically, the ortho-isomer showed very superior shape persistent, self-standing and self-healing properties compared to its meta - and pare-analogues. Interestingly, the healing process occurred without the need of involving oppositely charged species.
