Two pH-stable luminescent metal–organic frameworks (LMOFs), {[Ln2(L)2(OH)(HCOO)]·[H2O]}n (Ln = Eu 1, Tb 2), based on a new π-conjugated organic building block involving both carboxylate and terpyridine groups were rationally synthesized under a combination of hydro/solvothermal and ionothermal conditions (H2L = 4′-(4-(3,5-dicarboxylphenoxy)phenyl)-4,2′:6′,4′′-terpyridine). 1 and 2 are isostructural and feature noninterpenetrated open 3D condensed frameworks constructed by rod-shaped lanthanide-carboxylate building units. Their excellent water-stability and pH-stability allow them to be used in aquatic systems. 1 and 2 both exhibit selective and sensitive aqueous phase detection of the well-known nitroaromatic explosive environmental pollutant 2,4,6-trinitrophenol (TNP), which is highly desirable for practical applications. The presence of a free pyridine group on the LMOF particle surface was strategically utilized for the purpose of exclusive TNP-sensing.

离子液体介导的pH稳定的Eu和Tb有机构架用于水相检测2,4,6-三硝基苯酚（TNP）
基于新的两个pH稳定的发光金属有机骨架（LMOF），{[Ln 2（L）2（OH）（HCOO）]·[H 2 O]} n（Ln = Eu 1，Tb 2）在水/溶剂热和电离条件下（H 2 L = 4'-（4-（3,5-二羧基苯氧基）苯基）-4,2' ：6'，4''-三联吡啶）。1和2是同构结构，并具有由杆状镧系元素羧酸盐建筑单元构建的不互穿的开放3D压缩框架。它们出色的水稳定性和pH稳定性使其可用于水生系统。图1和图2均展示了对众所周知的硝基芳族爆炸性环境污染物2,4,6-三硝基苯酚（TNP）的选择性和灵敏水相检测，这对于实际应用是非常需要的。LMOF颗粒表面上游离吡啶基的存在被战略性地用于专门的TNP传感。
