Thermodynamic and thermal properties of the C60-l-Arg derivative

The paper presents experimental and DFT simulated data on temperature dependence of heat capacity for C60-l-arginine derivative. Smoothed Cp,m∘Tvalues in the temperature range from T → 0 K to 320 K are presented along with the values of standard thermodynamic functions: Sm°, [Hm∘T-Hm∘0] and [Φm∘T-Φm∘0]. In addition, the molar third law entropy and the molar formation entropy of the C60-l-arginine derivative in crystalline state at T = 298.15 K are calculated. The data on complex thermal analysis reveal that the C60-l-arginine derivative is stable up to 340 K. Further increasing of temperature leads to destruction of l-arginine groups and oxidation of fullerene core.
