Hyper-cross-linked polymers (HCPs) are one of the most important subclasses of the microporous organic polymers (MOPs), which is widely used due to the fast kinetics to form rigid frameworks. Unlike the conventional templet approaches to tune the morphology of HCPs, varying monomer–external cross-linker ratios enables to harmonize the morphogenesis of polymers. Herein we demonstrate template free approach for hyper-cross-linking of biphenyl-based polymer by a FeCl3 catalyzed Friedel−Crafts polymerization with formaldehyde dimethyl acetal (FDA). It was found that the monomer-FDA concentration play crucial role to form tubular, fibrous and wrinkled-micro particles. Owing to the high surface area, strong organic framework and tuned morphologies, the obtained the hyper-cross-linked polybiphenyl (HCPBPy) exhibit the outstanding adsorption capacity and efficiency towards p-cresol. |
