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）扩展为三个三重互穿的三维配位聚合物（R = 3-吡啶基），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cds-a（增广的CdSO 4）网络（2-NO3、2-ClO 4、2-BF 4）。2-NO3、2-ClO 4和2-BF 4的光电子发射强度在固态下随温度的变化在很大的温度范围内呈线性变化，且灵敏度不同，这可能是由于这些超分子间的相互作用，特别是Ag···Ag相互作用的增强。这些配合物是应用于温度传感器件的潜在候选者。
Dinuclear gridlike AgIstructural 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 of2‐NO3,2‐ClO4, and2‐BF4exhibit linear variations with temperature over large temperature ranges in the solid state with different sensitivities, which are tentatively attributed to these multiple supramolecular interactions, especially the enhanced Ag···Ag interactions. These complexes are potential candidates for applications in temperature‐sensing devices.
