Janus particles (JPs) self-assembled by a typical small organic gemini surfactant in water were reported by us. After the addition of a small amount Noyori-type organometallics to an organic solvent, these gourd-shaped JPs became new nanostructures, such as nanotubes (NTs), nanoribbons (NRs), and new types of JPs. Significant changes in specific rotation occurred on the solution-like samples, triggered by chiral organometallics in 20 μL of ethyl acetate. Almost all of these organometallics-triggered nanostructures can be conveniently detached and reversed within 5 min due to the easy-phase separation of ethyl acetate from the emulsion and the chemical-selective unstable binding between the organometallics and carbonate group on the surfactant.

由 Noyori 型有机金属触发的可切换纳米结构

我们报道了由典型的小型有机双子表面活性剂在水中自组装的 Janus 粒子 (JPs)。在有机溶剂中加入少量野依式有机金属后，这些葫芦形 JPs 成为新的纳米结构，如纳米管 (NTs)、纳米带 (NRs) 和新型 JPs。在 20 μL 乙酸乙酯中，由手性有机金属触发，类溶液样品的比旋度发生显着变化。几乎所有这些有机金属触发的纳米结构都可以在 5 分钟内方便地分离和逆转，这是由于乙酸乙酯从乳液中容易相分离以及有机金属和表面活性剂上的碳酸酯基团之间的化学选择性不稳定结合。
