Abstract

Lanthanide-based light-emitting coordination polymers (CPs) and CP gels (CPGs) have significance for applications in optical systems, image processing/multiplexing, and optical sensors. In this study, we report two new luminescent CPs (EuL-CP (1) and TbL-CP (2)) and CPGs (EuL-gel (5) and TbL-gel (6)) using lanthanide(III) ions (Ln(III) = Eu(III) and Tb(III)) and 4-(4-carboxyphenyl)-2,2:6,2-terpyridine ligand (L) capable of forming stable thermoreversible gels. Probable structures of EuL-CP (1) and TbL-CP (2) and the formations of EuL-gel (5) and TbL-gel (6) are proposed based on adequate computational studies. The CPGs are stimuli-responsive and could be utilized as invisible security inks for encryption. Further, poly(methyl methacrylate) (PMMA) polymer doped with respective CPs (0.75 wt %) is found to be suitable for forming composite films with UV-shielding properties.

发光配位聚合物：刺激响应凝胶、基于 PMMA 的复合薄膜和紫外线屏蔽

基于镧系元素的发光配位聚合物（CPs）和配位聚合物凝胶（CPGs）在光学系统、图像处理/多路复用和光学传感器中具有重要的应用价值。在本研究中，我们报告了两种新型发光配位聚合物（EuL-CP (1) 和 TbL-CP (2)）和 CPG（EuL-凝胶 (5) 和 TbL-凝胶 (6)），它们使用了镧系元素（III）离子（Ln(III) = Eu(III) 和 Tb(III)）和 4-(4-羧基苯基)-2,2:6,2-三吡啶配体（L），能够形成稳定的热可逆凝胶。根据充分的计算研究，提出了 EuL-CP (1) 和 TbL-CP (2) 的可能结构以及 EuL 凝胶 (5) 和 TbL 凝胶 (6) 的形成。这些 CPG 具有刺激响应性，可用作加密的隐形安全油墨。此外，还发现掺杂了相应氯化石蜡（0.75 wt %）的聚甲基丙烯酸甲酯（PMMA）聚合物适用于形成具有紫外线屏蔽特性的复合薄膜。
