Evolution of Spherical Assemblies to Fibrous Networked Pd(II) Metallogels fro…

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 mo…
