Abstract

Two new tetracationic hetero-bimetallacycles were prepared from a bis-pyridine amide ligand and metal (Pd and Pt) acceptors. We found that both self-assembled hetero-bimetallacycles bind and unwind supercoiled DNA as established by photophysical and gel electrophoresis analyses, respectively.

摘要

通过双吡啶酰胺配体和金属（钯和铂）受体合成了两种新型的四价阳离子杂双金属环。我们发现，通过光物理分析和凝胶电泳分析分别证实，这两种自组装的杂双金属环均能结合并解开超螺旋DNA。
