摘要:

采用自由基聚合法制备了具有光致发光特性的自愈合水凝胶, 解决了光致发光配合物在水相荧光猝灭的问题. 通过分子设计, 利用共价键将油溶性的含Eu稀土配合物引进水凝胶体系中, 发现该配合物在水凝胶体系中稳定存在, 不扩散. 含Eu稀土配合物具有紫外光致发光的特性, 赋予该水凝胶良好的可识别性. 同时该水凝胶含有动态硼酸酯键, 其快速愈合的特性使该水凝胶在受损后能短时间内修复损伤, 为制备可发光水凝胶和可识别生物医用材料提供了新的思路.

关键词: 水凝胶, 光致发光, 硼酸酯键, 自愈合, 稀土配合物

Abstract:

Self-healing hydrogels with photoluminescence properties were prepared by free radical polymerization, which solved the fluorescence quenching problem of photoluminescence complexes in water phase. The oil-soluble Eu-containing rare earth complex is introduced into the hydrogel system by designing a covalent bond, and the complex is stable and non-diffusion in the hydrogel system. The Eu-containing rare earth complex has the characteristics of ultraviolet photoluminescence, which endows the hydrogel with good recognizability. At the same time, the hydrogel contains dynamic borate ester bonds, and its fast-healing properties enable the hydrogel to repair the damage in a short time when it is damaged, which provides a new idea for the preparation of luminescent hydrogel and identifiable biomedical materials.

Key words: Hydrogel, Photoluminescence, Borate ester linkage, Self-healing, Rare earth complex
