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 CP 凝胶 (CPG) 在光学系统、图像处理/多路复用和光学传感器中的应用具有重要意义。在这项研究中,我们报道了两种新的发光 CP (EuL-CP (1) 和 TbL-CP (2)) 和 CPG (EuL-凝胶 (5) 和 TbL-凝胶 (6)) 使用镧系元素 (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。EuL-CP (1) 和 TbL-CP (2) 的可能结构以及 EuL-gel (5) 和 TbL-gel (6) 的形成是基于充分的计算研究提出的。CPG 具有刺激响应功能,可用作加密的隐形安全油墨。此外,发现掺杂有相应 CP (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性能的复合薄膜。
