Dinuclear gridlike AgI structural units (1) based on (3-pyridyl)-5-R-pyrazole ligands are extended from oligomers (R = phenyl) to three threefold interpenetrated 3D coordination polymers (R = 3-pyridyl) with cds-a (augmented CdSO4) networks (2-NO3, 2-ClO4, 2-BF4) linked through multiple supramolecular interactions (Ag–ligand, Ag–anion, Ag···Ag, and π–π interactions). The photoemission intensities of 2-NO3
基于 (3-吡啶基)-5-R-吡唑配体的双核网格状 AgI 结构单元 (1) 从低聚物 (R = 苯基) 扩展到三个三重互穿 3D 配位聚合物 (R = 3-吡啶基) 与 cds-a (增强的 CdSO4) 网络(2-NO3、2-ClO4、2-BF4)通过多种超分子相互作用(Ag-配体、Ag-阴离子、Ag…Ag 和 π-π 相互作用)连接。2-NO3、2-ClO4 和 2-BF4 的光发射强度在大温度范围内随温度呈线性变化,具有不同的灵敏度,这初步归因于这些多重超分子相互作用,尤其是增强的 Ag…… Ag 相互作用。这些复合物是温度传感设备应用的潜在候选者。
