A series of new dendritic platinum bisferrocenylacetylide complexes have been synthesized utilizing the coupling reaction of trans-Pt complexes with C–H bonds in alkynes as key steps. These new bimetallic dendrimers were fully characterized by multinuclear NMR (1H, 13C, and 31P) and mass spectrometry (MALDI-TOF-MS and CSI-TOF-MS). Electrochemical studies of these complexes were carried out and revealed that all of the redox moieties are stable, independent, and electrochemically active. In addition, all metallodendrimers show one-electron reaction responses, and the increased sizes of these complexes did not exhibit a dramatic influence on the diffusion coefficient.
一系列新的树枝状铂双二茂铁基乙炔基化合物已经合成,利用转型铂配合物与炔烃中的C-H键偶联反应作为关键步骤。这些新的双金属树状化合物通过多核NMR(1H、13C和31P)和质谱分析(MALDI-TOF-MS和CSI-TOF-MS)进行了全面表征。对这些化合物的电化学研究表明,所有氧化还原基团都是稳定的、独立的和具有电化学活性的。此外,所有金属树状化合物均显示出单电子反应响应,这些化合物的尺寸增加并未对扩散系数产生显著影响。
