Evolution of Spherical Assemblies to Fibrous Networked Pd(II) Metallogels from a Pyridine-Based Tripodal Ligand and Their Catalytic Property

---

A series of metal-organic gels (MOGs) were formed in CH3OH-CHCl3 solution based on L1 and
Pd(COD)(NO3)2 (L1 ) 4,4′,4′′-(1,3,5-triazine-2,4,6-triyl)tris(N-(pyridin-3-ylmethyl)benzamide, COD )
cycloocta-1,5-diene) at different ratios. FT-IR, NMR, and fluorescence spectroscopy show that hydrogen
bonding, π-π interaction, and coordination bonding are involved in the gel formation. The morphologies
of these metallogels are Pd/L1 ratio dependent ranging from spheres to fibers. The fibrous networked gel
shows higher catalytic activity in Suzuki-Miyaura coupling reaction than the spherical gel, acting as
recyclable Pd(II) catalyst supported by the air-stable networked gel/xerogel.
