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.

由选择性金属离子自组装双三联吡啶络合物构建的自修复有机凝胶和水凝胶

摘要 以三联吡啶为基础的凝胶由于其易于合成和可调节的特性而代表了一种新型的金属凝胶。然而，它们中很少有人能形成具有显着自愈特性的超级凝胶。在此，设计了一种新型的双三联吡啶络合物，命名为 BDT，它可以在选择性金属离子盐的存在下形成具有出色自愈能力的水凝胶和有机凝胶。有趣的是，DMF 中的 Cu2+-BDT 超级凝胶（CGC=0.19 wt%）显示出室温凝胶化、可注射和自愈能力。这些凝胶的特征在于 UV-vis、SEM、TEM 以及流变学实验。
