Abstract

Three fluorescent Zn coordaintion polymers (CPs) have been synthesized from the reactions of Zn(NO3)2∙6H2O, benzene-1,4-dicarboxylic acid (1,4-H2bdc), and angular carbazole-derived bispyridyl ligands (Cz-3,6-bpy or Cz-Pr-3,6-bpy). CPs 1-3 all adopt similar two-dimensional (2D) ring-and-rod layer structures, described as topologically 4-connected 2∙65 nets where the Zn(II) centers act as 4-connected nodes. CPs 1 and 2 are a pair of solvent-mediated supramolecular isomers where the former shows a two-fold interlocked 2D → 2D polyrotaxane-like entangled net and the latter reveals a four-fold interpenetrated 2D → 3D polyrotaxane entanglement. CP 3 is structure analgue of 1. The formation of 1-3 implies the realization of interpenetration control and supramolecular isomerism in polyrotaxanes by fine-tuning the solvent compositions and ligand steric-modulation. CPs 1-3 all show high thermal stability approaching 400 °C and good chemical stability in various solvents at room temperature for 24 h. Further, CPs 1-3 all are excellent turn-off sensors to recognize Fe3+ in water with high selectivity and sensitivity, great anti-inference ability, and low limit of detection (LOD). The sensing mechanisms are found to be competitive absorption of excitation wavelength energy and the occurrence of framework-Fe3+ interactions.

通过溶剂组成和配体空间调节控制金属-有机聚轮烷的互穿:超分子异构体和Fe3+离子的发光检测。
以Zn(NO3)2∙6H2O、苯-1,4-二羧酸(1,4- h2bdc)和角咔唑衍生的双吡啶配体(cz -3,6-bpy或cz - pr -3,6-bpy)为原料,合成了3种荧光Zn配位聚合物(CPs)。CPs 1-3都采用类似的二维(2D)环杆层结构,被描述为拓扑4-连接的2∙65网,其中Zn(II)中心充当4-连接节点。CPs 1和CPs 2是一对溶剂介导的超分子异构体,前者表现为二维互穿的二维聚轮烷类纠缠网,后者表现为二维互穿的三维聚轮烷类纠缠网。cp3的结构类似于1。1-3的形成意味着通过调整溶剂组成和配体的空间调节,实现了聚轮烷的互穿控制和超分子异构。CPs 1-3在接近400°C时具有较高的热稳定性,在室温下在各种溶剂中具有24 h的良好化学稳定性。此外,CPs 1-3都是识别水中Fe3+的优秀关闭传感器,具有高选择性和灵敏度,抗推断能力强,低检测限(LOD)。发现其传感机制是激发波长能量的竞争吸收和框架- fe3 +相互作用的发生。
