The reaction of tetrasodium-4,4',6,6'-tetracarboxy-2,2'-bipyridine (Na(4)L) with various lanthanide ions yields a family of isostructural supramolecular {Na(2)[Ln(2)L(2)]} complexes (1-4), where Ln(III) = Eu, Nd, Gd, and Tb. Strikingly, these complexes luminesce in buffered H(2)O or D(2)O solutions in either the visible or near-IR regions, despite their high hydration states.
四钠-4,4',6,6'-四羧酸-2,2'-联吡啶（Na(4)L）与各种镧系元素离子的反应生成了一系列结构相同的超分子{Na(2)[Ln(2)L(2)]}配合物（1-4），其中 Ln(III) = Eu、Nd、Gd 和 Tb。值得注意的是，尽管这些配合物具有高水合状态，但它们在缓冲的 H(2)O 或 D(2)O 溶液中仍在可见或近红外区域发光。
