Magnetite Nanoparticle-supported Coordination Polymer Nanofibers: Synthesis and Catalytic Application in Suzuki-Miyaura Coupling

Functional nanoscale coordination polymers are receiving growing scientific interest because of their potential applications in many domains. In this paper, we demonstrated that a nanofibrous networked metal-organic gel (G1-MNPs) was formed by simply mixing 4,4',4''-(1,3,5-triazine-2,4,6-triyl)tris(N-(pyridin-3-ylmethyl)benzamide) (L) and Pd(COD)(NO(3))(2) in CHCl(3)-MeOH with a Pd/L molar ratio of 1:1 in the presence of magnetite nanoparticle (MNPs). The self-assembly behavior of nanofibers was not significantly effected by the introduction of magnetite nanoparticles. The xerogel of G1-MNPs was superparamagnetic and showed catalytic activity in Suzuki-Miyaura C-C coupling reactions. The Pd(II) xerogel could be magnetically isolated and recycled with a permanent magnet. It represents a novel strategy to introduce nanoparticles into functional coordination polymers for multifunctional materials.
