Abstract

We report here our successful attempt to obtain self-healing supramolecular hydrogels with new metal-containing monomers (MCMs) with pendent 4-phenyl-2,2':6',2″-terpyridine metal complexes as reversible moieties by free radical copolymerization of MCMs with vinyl monomers, such as acrylic acid and acrylamide. The resulting metal-polymer hydrogels demonstrate a developed system of hydrogen, coordination and electron-complementary π-π stacking interactions, which play a critical role in achieving self-healing. Kinetic data show that the addition of a third metal-containing comonomer to the system decreases the initial polymerization rate, which is due to the specific effect of the metal group located in close proximity of the active center on the growth of radicals.

摘要

我们在此报告了一项成功的尝试，即通过含金属的新型单体（MCMs）与丙烯酸和丙烯酰胺等乙烯基单体进行自由基共聚，获得具有作为可逆部分的带有4-苯基-2,2':6',2″-三联吡啶金属配合物侧基的自愈合超分子水凝胶。所得的金属-聚合物水凝胶展现出发达的氢键、配位键和电子互补π-π堆积相互作用体系，这些相互作用在实现自愈合方面起着关键作用。动力学数据表明，向体系中添加第三种含金属共聚单体可降低初始聚合速率，这是由于位于活性中心附近的金属基团对自由基生长的特定影响所致。
