Two new zinc(II) complexes, namely, [Zn(BBOP)(TPA)] () and [Zn(BBOP)(NDC)·HO] () (HTPA = terephthalic acid, HNDC = 1,4-naphthalene dicarboxylic acid, BBOP = 1,3-bis(benzimidazol-2-yl)-2-oxapropane) are hydrothermally synthesized and characterized. features a 3D 2-fold interpenetrated 3-connected SrSi-type framework. is a mononuclear Zn(II) complex and further extend into the 3D supramolecular framework by OH⋯O and NH⋯O hydrogen bonding interactions. and both manifest high chemical stability. Two luminescence complexes are excellent sensors for the luminescent detection of Fe, CrO, and CrO ions in an aqueous medium. The quenching mechanism of the complexes is also investigated.

两种坚固的锌 (II) 配合物作为多功能发光传感器，用于检测水中的 Fe3+、Cr2O72− 和 CrO42− 离子


两种新的锌(II)络合物，即[Zn(BBOP)(TPA)] () 和 [Zn(BBOP)(NDC)·H2O] () (HTPA = 对苯二甲酸，HNDC = 1,4-萘二甲酸，BBOP=1,3-双(苯并咪唑-2-基)-2-氧杂丙烷)是水热合成和表征的。具有 3D 2 重互穿 3 连接 SrSi 型框架。是单核 Zn(II) 配合物，并通过 OH⋯O 和 NH⋯O 氢键相互作用进一步延伸到 3D 超分子框架中。并且两者都表现出很高的化学稳定性。两种发光复合物是用于发光检测水介质中 Fe、CrO 和 CrO 离子的优异传感器。还研究了配合物的猝灭机制。
