Figure 4. A schematic representation of the synthesis of molecularly imprinted polymers (MIPs) based on quantum dot-grafted covalent organic frameworks (QD-grafted COFs) for optosensing of ferulic acid (FA). Tetraethyl orthosilicate (TEOS) and (3-aminopropyl) triethoxysilane (APTES) are used as cross-linker and functional monomer, respectively, in MIP fabrication process. Reprinted with permission[63].
