By subsequently running a program that maintained the temperature at -40°C for 10 min, the initial temperature of the next heating measurement could be started at -40°C. The peak temperature of the exothermic peak shifted to higher temperatures as the heating rate increased, indicating typical cold crystalline behavior. The crystallization energies of cold crystallization were calculated using Equation 1 after creating a Kissinger plot with the Kissinger equation (Figure in the Supporting Information). The crystallization energies were calculated to be 46, 217, 229, 528, 356, and 336 KJ mol -1 for compounds 1-6, respectively. Crystalline samples with low crystallinity tend to have smaller crystallization energies. For example, C10GL ( ) is crystalline because of the van der Waals forces from the fatty acid chain, but its short chain length and high degree of freedom result in lower crystallinity and smaller crystallization energy. C16GL (4) (palmitic acid with 16 carbons) has the highest crystallization energy, while compounds C18GL (5) and C22GL (6) with longer carbon chains exhibit decreasing crystallization energies. This suggests that 16-carbon palmitic acid has the highest intermolecular packing strength, whereas increasing carbon chain length makes packing more difficult, reducing the crystallinity and crystallization energy.
