Using Fourier-transform infrared spectroscopy (FT-IR), a kinetic study was conducted on the self-assembly of a C22 tailed bisurea organogelator in benzene. Solid organogelator was dissolved in benzene with heat, the resulting sol was placed in a FT-IR liquid cell with sodium chloride windows, and spectra were acquired at one minute intervals. In the amide II band, three peaks were observed, corresponding to three hydrogen bonding states of urea; free (or unbound), singly bound, and doubly bound. By analyzing the areas of these peaks, a relative decrease in free urea, and corresponding increases in bound ureas were observed as time increased. It was determined that assembly occurs in the first 20 minutes, both spectroscopically and macroscopically. Higher concentrations exhibited more rapid assemby, consistent with a nucleation and growth mechanism.
