The study of the inherent factors that influence the isolation of one type of metallosupramolecular architecture over another is one of the main objectives in the field of Metallosupramolecular Chemistry. In this work, we report two new neutral copper(II) helicates, [Cu(L)]·4CHCN and [Cu(L)]·CHCN, obtained by means of an electrochemical methodology and derived from two Schiff-based strands functionalized with ortho and para-t-butyl groups on the aromatic surface. These small modifications let us explore the relationship between the ligand design and the structure of the extended metallosupramolecular architecture. The magnetic properties of the Cu(II) helicates were explored by Electron Paramagnetic Resonance (EPR) spectroscopy and Direct Current (DC) magnetic susceptibility measurements.
研究影响金属超分子架构分离的内在因素是金属超分子化学领域的主要目标之一。在这项工作中，我们通过电化学方法得到了两个新的中性铜（II）螺旋体[Cu(L)]·4CHCN 和 [Cu(L)]·CHCN，它们是由两个基于席夫碱的链衍生而来的，在芳香表面上对位和邻位带有叔丁基。这些微小的修饰使我们能够探索配体设计与扩展金属超分子架构结构之间的关系。通过电子顺磁共振（EPR）光谱和直流（DC）磁化率测量研究了 Cu(II)螺旋体的磁性。
