摘要：
The mono-adducts of C-70 fullerene with pentacene, tetracene and antracene were synthesized. The C-70/acene adducts were studied with FT-IR and the electronic absorption spectroscopy. Thermogravimetric analysis (TGA) in combination with derivative thermogravimetry (DTG) and differential thermal analysis (DTA) were employed to determine the quantitative composition of the adducts and their relative thermal stability. Differential scanning calorimetry (DSC) was employed as well for the determination of the stability of the adducts. It was found that the C-70/acene adducts decompose with endothermal reactions. The enthalpy of the decomposition reaction and the decomposition temperatures were determined and found in agreement with the DTG and DTA results.
