  摘要：

  测量快速移动或小规模样品的挑战在于样品与传感器之间没有接触。镧系元素接枝到杂化材料上已成为获得无创温度计最有希望的精确技术之一。在这项工作中，研究了一种新型的联吡啶基多孔有机聚合物（bpyDAT POP）作为Eu（acac）3和Tb（acac）3络合物接枝后的温度传感器。bpyDAT POP成功显示出10-310 K范围内的温度依赖性行为，证明了无定形，多孔有机骨架的潜力。我们观察到了独特的温度依赖性行为。更有趣的是，由于Eu 3+和Tb的温度变化，观察到的排放变化不是标准的变化3+时，Tb 3+的发射光谱保持恒定。这项工作为观察到的现象提供了基于框架和能量的解释。bpyDAT POP框架中的共轭被中断，从而创建了能量隔离的Tb 3+环境。因此，不存在从Tb 3+到Eu 3+的能量转移，也没有检测到从Tb 3+到bpyDAT POP配体的能量反向转移（即没有热猝灭）。

• Syntheses and Structures of Isomeric Diaminotriazinyl-Substituted 2,2′-Bipyridines and 1,10-Phenanthrolines

  Isomeric 2,2'-bipyridines 4a-6a and 1,10-phenanthrolines 7a-9a with two diaminotriazinyl (DAT) substituents were synthesized to explore their dual ability to direct association by the chelation of metals and the characteristic hydrogen bonding of DAT groups. Crystals of compounds 4a-6a and 7a-9a were grown under diverse conditions, and their structures were solved by X-ray crystallography. Analysis revealed multiple shared features analogous to those observed in the structures of simpler DAT-substituted pyridines 1-3. For example, the bipyridines and phenanthrolines favor flattened conformations except in the cases of compounds 8a and 9a, where the patterns of substitution prevent the DAT groups from lying in the plane of the phenanthroline core. As expected, the DAT groups form approximately coplanar hydrogen bonds according to standard motifs I-III, which play a key role in directing molecular organization. However, the structures of simple pyridines 1-3, which favor efficiently packed chains and sheets, differ predictably from those of bipyridines 4a-6a and phenanthrolines 7a-9a in two ways: (1) The larger number of DAT groups in compounds 4a-9a typically leads to complex three-dimensional networks held together by a larger number of hydrogen bonds per molecule, and (2) the need to respect multiple directional interactions prevents compounds 4a-9a from forming closely packed structures, and significant quantities of guests are included. Together, these observations confirm the effectiveness of incorporating special groups such as DAT within more complex molecular structures to control association according to reliable patterns. Bipyridines 4a-6a and phenanthrolines 7a-9a promise to be particularly rich sources of new supramolecular chemistry because they have well-defined molecular topologies and a dual ability to direct association by chelating metals and by engaging in multiple hydrogen bonds according to reliable patterns.

More intriguingly, instead of the standard observed change in emission as a result of a change in temperature for both Eu3+ and Tb3+, the emission spectrum of Tb3+ remained constant.
