摘要

我们合成了基于三（2-吡啶基甲基）胺 TPMA 结构的一系列新的稳定的含自由基多位配体及其相应的金属配合物。这些分子体系为研究金属离子和有机自由基等各种自旋载体如何主要通过峰高 d1/d 的经验比来影响其 EPR 特性提供了可能。此外，还可以分析分子骨架中 TEMPO 自由基单元的不同构象如何影响金属体系。

Synthesis and EPR Studies of Zinc and Copper Tris(2‐pyridylmethyl)amines (TPMA) Metal Complexes Containing TEMPO Functionalities

A new family of stable radical‐containing polytopic ligands based on tris(2‐pyridylmethyl)amines TPMA architecture and their corresponding metal complexes have been synthesized. These molecular systems offered the possibility to investigate how various spin carriers, such as the metal ion and the organic radical, influence their EPR properties mainly through the empirical ratio of peak heights d₁/d. Moreover, it has been possible to analyze how different conformations of TEMPO radical units in the molecular skeleton affect the metallic system.
