This work reports the effect of Pd(II) as chemical effector on an acylhydrazone-based dynamic covalent library (DCL) in biphasic systems (water/chloroform). The constituents of the DCL are self-built and distributed in the two phases, two of them are lipophilic enough to play the role of a carrier agent that may transfer Pd(II) from the aqueous phase to the organic phase. Upon addition of Pd(II), the DCL of components exhibits a strong amplification of the constituent that is the most adapted to stabilize Pd(II) in chloroform as well as its agonist in water. This evolution is driven by the combination of the interaction of the DCL with Pd(II) and the presence of the two phases. This study paves the way to a novel approach for liquid/liquid extraction and metal recovery by means of adaptive extractant species generated in situ by a DCL.
本工作报道了Pd(II)作为化学效应剂对双相体系（水/氯仿）中基于酰腙的动态共价库（DCL）的影响。DCL的成分是自行构建并分布在两相中的，其中两种成分具有足够的亲脂性，能够起到载体的作用，将Pd(II)从水相转移到有机相。加入Pd(II)后，组分的DCL对最适合在氯仿中稳定Pd(II)及其在水中的激动剂的成分表现出强烈的放大作用。这种演变是由DCL与Pd(II)的相互作用以及两相的存在共同驱动的。本研究为通过DCL原位生成的适应性萃取剂物种进行液/液萃取和金属回收的新方法铺平了道路。
