Self-Assembled Microfibers of Simple Amphiphilic Molecules Through a Facile Precipitation Route

One-dimensional (1D) fiber structures of simple amphiphilic molecules were prepared through a facile precipitation route. The self-assembly process was studied by ultraviolet-visible absorption and Fourier transform infrared) spectroscopy, which indicated that hydrogen bonding interactions played a role in the1D growth along the axis of the fiber. The water content, self-assembling temperature, and concentration of 1,5-bis-(1-(pyridin-2-yl)ethylidene)thiocarbonohydrazide molecules in the solution had obvious effects on the size and morphology of the self-assembled products. The formation of1D superstructures is not only of a hot subject in the process of nanoscience but also opens a new venue for conveniently controlling self-assembled structures of similar organic molecules.
