Polymers containing triazolylbiferrocene are synthesized by ROMP or radical chain reactions and react with HAuCl4 to provide class-2 mixed-valent triazolylbiferrocenium polyelectrolyte networks (observed inter alia by TEM and AFM) that encapsulate gold nanoparticles (AuNPs). With triazolylbiferrocenium in the side polymer chain, the intertwined polymer networks form nanosnakes, unlike with triazolylbiferrocenium in the main polymer chain. By contrast, simple ferrocene-containing polymers do not form such a ferricenium network upon reaction with Au(III), but only small AuNPs, showing that the triazolyl ligand, the cationic charge, and the biferrocenium structure are coresponsible for such network formations.
含三唑基双二茂铁聚合物通过 ROMP 或自由基链反应合成，并与 HAuCl4 反应，提供 2 类混合价态三唑基双二茂铁聚电解质网络（通过 TEM 和 AFM 观察到），该网络包埋了金纳米粒子（AuNPs）。在侧链聚合物中含有三唑基双二茂铁，相互交织的聚合物网络形成纳米蛇，而在主链聚合物中含有三唑基双二茂铁则不会形成这样的二茂铁网络。相比之下，与 Au(III) 反应时，简单的含二茂铁聚合物不会形成这样的铁络合物网络，而只会形成小的 AuNPs，这表明三唑配体、阳离子电荷和双二茂铁结构共同导致了这种网络的形成。
