Precise Control of Self-Association of Open-Shell Species toward Construction of Conducting Supramolecular Wires

具有开壳电子结构的自共轭低聚物作为相应导电聚合物的模型已经得到了广泛的研究，但有关现象的细节仍有待阐明。此外，近年来人们对利用这种自结合的超分子化学越来越感兴趣。在这项研究中，基于我们最初设计的寡硫吩，我们揭示了结构和驱动自缔合的因素之间的关系，并成功地观察了通过金纳米颗粒的氧化还原开关和指示物的双自由基特征。

Self- -conjugated oligomers with open-shell electronic structure has been intnsively investigated as models of corresponding conducting polymers, but the details about the phenomena remains to be elucidated. In addition, recent years have witnessed a growing interest in supramolecular chemistry using such self-associations. In this study, based on our originally designed oligothiophenes, we have revealed relationship between structure and factors driving the self-association and have succeeded in the observations of redox-switching via gold nanoparticles and biradical character of dications.
