## 1 Introduction
Although such MIPs have high affinity and selectivity, their adsorption capacity and precision for target molecule adsorption sites need to be improved. In order to achieve the rapid \"capture\" of PEDCs by MIPs, MIPs are prepared into two-dimensional film structures by surface molecular imprinting [31; 32; 33; 34; 35], which can avoid the \"leakage\" of template molecules that may occur during the adsorption process of conventional three-dimensional MIPs [36; 37; 38], and improving the selectivity and sensitivity of MIPs films to target molecules, thus enabling fast and accurate selective identification of PEDCs in adsorbed aqueous environments [39; 40; 41]. Graphene has received widespread attention for its unique two-dimensional nanostructure and holds great promise for application in the field of nanoscience and technology [42]. Due to the limitations of existing physical methods, chemical modifications are usually used to further improve the physicochemical properties of graphene [43]. Research on functionalized graphene composites synthesized by selecting graphene materials as a matrix and combining them with nanoparticles, polymer materials, and magnetic materials is developing rapidly [44]. The composites combine many properties of graphene materials and functional molecules, demonstrate good biocompatibility, and are widely used in research fields such as electrochemistry, biology, and materials science [45]. Among them, magnetic graphene-based materials have proven to be a simple, convenient and effective method for the separation and purification of biological samples and the removal of organic contaminants from the aqueous environment because of the unique magnetic properties of magnetic materials and their ability to be separated from samples under the action of an applied magnetic field [46]. In our previous research work, we explored the interactions between graphene, functional monomers, and template molecules using density flooding theory simulations and found that the introduction of graphene provides a significant \(\pi\) surface that can overlap with the \(\pi\) orbitals of template molecules and the resulting \(\pi\)-\(\pi\) conjugation effect can enhance the stability of the functional monomers and template molecules bound to each other [47]. On the other hand, metal-organic frameworks (MOFs) are emerging porous materials that have been explored as efficient adsorbents due to their ultra-high surface area, high porosity, tunable pore structure, and chemical modification capabilities and have become a research hotspot in many fields [48; 49; 50; 51]. Among them, zeolitic imidazolate frameworks are a class of MOFs with zeolite topology formed by ligating nitrogen-containing heterocyclic imidazoles and their derivatives with metal ions. [PERSON] et al. reported that a highly sensitive and selective doubly imprinted polymer-modified electrochemical sensor based on a copper metal-organic framework/mesoporous carbon (Cu-MOF/MC) composite was developed for the simultaneous determination of rifampicin (RIF) and isoniaizid (INZ) [52]. Compared with MOFs, ZIFs have higher thermal stability and adsorption capacity, and the composites combining them with functional materials such as graphene and magnetic nanoparticles have higher adsorption capacity and magnetic separation performance [53; 54; 55; 56]. Among them, ZIF-8 and ZIF-7, which are ligand-bound to imidazole-like anions via Zn\({}^{2+}\), are typical framework structures among many ZIFs materials. [PERSON] et al. successfully prepared molecularly imprinted hybrid materials with good selective recognition of 2,4-dichlorophenoxyoxyacetic acid (2,4-D) by combining ZIF-8 with MIPs by emulsion polymerization [57].
