Copper complexes bearing ligands based on tris(2-methylpyridyl)amine (TPMA) are leading catalysts in atom transfer radical polymerization (ATRP). In recent years, the TPMA structure has been finely modified to enhance the catalytic activity of the corresponding Cu complex. In this study, we report the synthesis of eight novel copper TPMA complexes, and the evaluation of the catalytic activity for electrochemically mediated ATRP in both organic and aqueous media. The TPMA skeleton was modified by inserting differently m-functionalised phenyl substituents. Complete characterizations and electrochemical investigations were performed to define the structural and redox properties of the new complexes and compare them to the archetype Cu/TPMA. Well-controlled polymerizations of some hydrophobic, hydrophilic and acidic monomers are presented, with conversions > 80%, low dispersity and predetermined molecular weights, thus confirming that these compounds are suitable ATRP catalysts for different systems.

带有基于三（2-甲基吡啶基）胺（TPMA）的配体的铜络合物是原子转移自由基聚合（ATRP）的主要催化剂。近年来，已经对TPMA结构进行了精细修饰，以增强相应Cu络合物的催化活性。在这项研究中，我们报告了八个新型铜TPMA配合物的合成，以及在有机和水性介质中对电化学介导的ATRP的催化活性的评估。的TPMA骨架是通过将不同修饰米-官能化的苯基取代基。进行了完整的表征和电化学研究，以定义新配合物的结构和氧化还原性质，并将其与原型Cu / TPMA进行比较。提出了一些疏水，亲水和酸性单体的受控聚合，转化率> 80％，低分散性和预定的分子量，因此证实了这些化合物适用于不同体系的ATRP催化剂。
