Abstract In this paper, we prepared a novel reactor with switchable ability to address present challenges in tandem catalyst. By introducing mussel-inspired moiety, this goal was achieved via preparing a “smart” polymer reactor which can open or closes the entry tunnel of the targeted substrate in cascade reactions. The catalyst consisted of two functional layers acting as tandem catalytic parts and one smart layer with mussel-inspired moieties as a controlled middle switch. The top and the bottom layer were made of molecularly imprinted polymers and catalytic components, like acidic parts and metal nanoparticles, respectively. The middle layer made of polymeric dopamine (PDPA) and acrylamide with self-healing ability will allow or inhibit the intermediate product for the reaction, thus controlling the process of the tandem catalysis. As a result, the novel catalyst exhibited self-controlled tandem catalysis, which provides new opportunities to design smart tandem catalysts, showing a promising prospect in this area.

面向具有夹层贻贝层开关的下一代“智能”串联催化剂

摘要 在本文中，我们制备了一种具有可切换能力的新型反应器，以应对串联催化剂的当前挑战。通过引入受贻贝启发的部分，这一目标是通过制备“智能”聚合物反应器实现的，该反应器可以在级联反应中打开或关闭目标底物的进入通道。该催化剂由两个作为串联催化部分的功能层和一个具有贻贝启发部分作为受控中间开关的智能层组成。顶层和底层分别由分子印迹聚合物和催化成分制成，如酸性部分和金属纳米颗粒。由具有自修复能力的聚合多巴胺（PDPA）和丙烯酰胺组成的中间层将允许或抑制中间产物进行反应，从而控制串联催化的过程。因此，
