The urgent needs for photoactive materials in industry drive fast evolution of synthetic procedures in many branches of chemistry, including the chemistry of silsesquioxanes. Here, we disclose an effective protocol for the synthesis of novel double-decker silsesquioxanes decorated with two (styrylethynylphenyl)terpyridine moieties (). The synthesis strategy involves a series of silylative and Sonogashira coupling reactions and is reported for the first time. were employed as nanocage ligands to promote self-assembly in the presence of transition metals (TM), i.e., Zn, Fe, and Eu ions, to form one-dimensional (1D) coordination polymeric nanofibers. Additionally, ultraviolet-promoted and reversible - isomerization of the C═C bond within the ligand structures may be exploited to tune their emission properties. These findings render such complexes promising candidates for applications in materials chemistry. This is the first example of 1D coordination polymers bearing DDSQ-based nodes with TM ions.
工业上对光活性材料的迫切需求推动了包括倍半硅氧烷化学在内的许多化学分支合成方法的快速发展。在此，我们公开了一种有效的合成方法，用于制备带有两个（苯乙烯基乙炔基苯基）三联吡啶基团的新型双层倍半硅氧烷（）。该合成策略涉及一系列硅烷化反应和Sonogashira偶联反应，且首次被报道。被用作纳米笼配体，以促进在过渡金属（TM）即锌、铁和铕离子存在下的自组装，形成一维（1D）配位聚合物纳米纤维。此外，配体结构内碳碳双键的紫外光促进和可逆的 - 异构化可用于调节其发光特性。这些发现使这类配合物成为材料化学应用中有前景的候选物。这是首个带有基于DDSQ的节点与TM离子的一维配位聚合物的例子。
