N2 - The highly directional interactions among complex gelators of 2,6-pyridinedicarboxylic acid and 4-hydroxypyridine are investigated, which lead to the formation of ordered one-dimensional fibers with diameters of 500 nm ∼ 2 μm. By scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, 1H nuclear magnetic resonance (1H NMR) spectroscopy, ultraviolet-visible (UV-vis) spectroscopy, and X-ray powder diffraction (XRD), the co-assembly of the complex into straight fibers under the function of multiple directional hydrogen bonds and π-π stackings is proved. The strong and directional interactions lead to rich dynamic behavior and high degrees of internal order among the complex gelators. The ordered one-dimensional co-assemblies possess useful functions in templated synthesis, molecular recognition, enzyme immobilization, and other biochemistry fields.
