Covalent organic polymers are an emerging class of materials with potential applications in areas including molecular separation, gas sorption, and catalysis. A novel fully conjugated organic polymer bearing bis(imino)pyridine (COP-BIP) and its catalytic function are reported here. Unlike previous COP materials, the imine bonds of COP-BIP act as both linkages and complexation sites for the binding of metal ions. A clear structure is presented based on ultraviolet-visible, Fourier transform infrared, and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry characterization. The COP-BIP materials are thermally stable up to 440 °C and are insoluble in conventional solvents. In addition, COP-BIP complexes Pd ions on bis(imino)pyridine sites and forms a heterogeneous catalyst, which exhibits excellent catalytic activity in the Suzuki-Miyaura C–C coupling reaction.
Graphical AbstractA conjugated organic polymer linked by imine bonds bearing bis(imino)pyridine (COP-BIP) was synthesized for the first time. The formation process and the precise structure was determined by MALDI-TOF mass spectrometry. COP-BIP showed highly thermal stability up to 440 °C and was insoluble in conventional solvents. It functioned as a ligand for Pd ion and formed a heterogeneous catalyst during the Suzuki-Miyaura C–C coupling reaction.Figure optionsDownload as PowerPoint slide
