tris-(2-Pyridylmethyl)amine (usually abbreviated as TPA or TPMA) are ligands which are emerging in many fields of chemistry because of their ability to form stable and catalytically active complexes with a wide variety of metals. While the applications in catalysis began soon after the synthesis of the first metal complexes, studies in supramolecular chemistry are more recent and they often take advantage from their stereodynamic nature. This review surveys TPMA applications as: i) anion sensors, ii) biochemical sensors, iii) molecular switches, iv) chiral probes and as v) building blocks in the synthesis of supramolecular cages.

三（2-吡啶基甲基）胺作为超分子化学中的新兴支架

三-（2-吡啶基甲基）胺（通常缩写为TPA或TPMA）是在化学领域中崭露头角的配体，因为它们能够与多种金属形成稳定的催化活性络合物。虽然催化的应用是在第一种金属配合物合成后不久就开始的，但超分子化学研究却是最近的，并且它们经常从其立体动力学性质中受益。这篇综述对TPMA的应用进行了调查：i）阴离子传感器，ii）生化传感器，iii）分子开关，iv）手性探针以及v）合成超分子笼子的基础。
