Pyrene-appended calix[2]triazole[2]arene capable of bimodal sensing has been synthesized. Upon addition of Zn2+ (or Cd2+), it selectively exhibits an enhanced monomeric emission (∼13–20-fold) over other metal ions. On the other hand, it displays excellent selectivity for Fe2+ over other metal ions (even over Fe3+) from the angle of excimeric emissions (10-fold enhancement). Density Functional Theory
A crown ether-appended calix[2]triazolium[2]arene, which exhibits excellent selectivity for H2PO4- compared to other anions, has been designed and synthesized. The selectivity of the prepared receptor for H2PO4- is caused by the stabilization of H2PO4- by the neighboring triazolium hydrogen bond donors and crown ether hydrogen bond acceptors.
设计并合成了冠状醚附加的杯[2]三唑鎓[2]芳烃,与其他阴离子相比,该化合物对H2PO4-具有优异的选择性。所制备的H 2 PO 4受体的选择性是由相邻的三唑鎓氢键供体和冠醚氢键受体对H 2 PO 4的稳定作用引起的。

A series of calix[2]triazole[2]arenes, which are members of the heterocalixarene family, were generated by copper(I)-catalyzed Huisgen reaction in a one-pot synthesis. Their various conformational structures and physical properties were characterized by a computational, NMR spectroscopic, and X-ray structural investigation. Among six conformations, the 1,2-alternate conformation was found to be the
一系列杯[2]三唑[2]芳烃是杂杯芳烃家族的成员,是通过铜(I)催化的Huisgen反应在一锅合成中产生的。它们的各种构象结构和物理性质通过计算、核磁共振光谱和 X 射线结构研究进行了表征。在六种构象中,由于酚羟基和三唑氮原子之间的两个分子内氢键,发现 1,2-交替构象是最稳定的。
