Abstract Terpyridine-based gels represent a new type of metallogels due to the facile synthesis and tunable properties. However, few of them could form super gel with remarkably self-healing properties. Herein, a novel kind of bis-terpyridine complex, named as BDT, is designed, which could form both hydrogels and organogels with outstanding self-healing ability in the presence of selective metal ion salts. Interestingly, the Cu2+-BDT super gel (with CGC=0.19 wt%) in DMF displays room temperature gelation, injectable and self-healing ability. These gels are characterized by UV–vis, SEM, TEM as well as rheology experiments.
