摘要:

报道了一种嵌有双亚胺基吡啶配体的全共轭有机聚合物材料. 该材料所具有的双亚胺基吡啶配体起到链接聚合物单元和络合金属中心的双重作用. 采用紫外可见光谱、红外光谱以及基质辅助激光解吸电离飞行时间质谱等对其结构进行了详细表征和确认. 由于具有全共轭结构,该材料的热稳定性达到440 ℃,并且在常规溶剂中较难溶解. 作为多相催化剂载体,可以络合Pd离子形成新的多相配位催化剂,在经典的Suzuki-Miyaura C-C偶联反应中转化率和选择性均达到99%.

Abstract:

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 ℃ 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.
