Abstract A smart catalytic reactor capable of simple/tandem-commutative catalytic ability was reported here. By borrowing the natural soft morphology and segregated zones in biosystems, this reactor was constructed with polymeric bilayer composites where each constituted a catalytic zone. The combination of the two catalytic zones with a catalytically-coupled process would dictate the reactor sequential catalytic behaviors and accordingly simple/tandem-commutative catalytic ability. To that end, one of the layers in this reactor was fabricated with acidic architectures capable of catalytic hydrolysis whereas the other layer was made of a thermo-sensitive antibody-like imprinted hydrogel which acted as a switch to provide access for the succeeding reaction. In this way, this reactor demonstrated the simple/tandem-commutative catalytic ability. This suggested design shares a promising prospect with developing functional catalysts and programmable catalytic processes.

1 Introduction The development of smart catalysts has always been an interesting subject in catalytic communities, regardless of the technological challenges [1, 2]. The use of smart catalysts enables the engaging catalytic processes to run in a controllable and programmable paradigm, dictating the catalytic systems one-pot synthetic-ability. This advantage often originates from the precise control of the structure–activity relationship in the ongoing catalysts, which leads to either autonomous access for substrates or microphase separation from the catalytic systems [3–5]. In this way, the use of smart catalysts leads to the occurrence of controllable catalytic behaviors. Over the years, intensive endeavors have been made in this field, concerning various smart carriers and brilliant architectures [6–8]. Nonetheless, the practical application of these smart catalysts has been not notable over the years. One important reason behind this lies in the complication of the practical catalytic processes, which * Songjun Li [email protected] http://polym.ujs.edu.cn/info/1021/1061.htm 1

often concurrently involve simple and tandem processes [9, 10]. These complicated conditions often desire these smart catalysts to be able to commutate forth-and-back between simple and tandem processes and programmably run without external meddlers. Unfortunately, this target is actually unreachable by resorting to currently available technology and methods. Hence, the appeal for new technology and methods has been remaining high.
