Abstract
The objective of this work is to obtain the thermodynamic parameters (the changes in enthalpy, Gibbs free energy, and entropy) of two degradation steps observed in three novel families of organometallic dendrimers. The isoconversional Flynn–Wall–Ozawa (FWO) model was employed to calculate the effective activation energy and pre-exponential factor. The changes in enthalpy and the entropy revealed a quite consistent tendency with the activation energy whereas the change of Gibbs free energy always remained positive during the whole degradation process, which demonstrated the implication that the degradation is non-spontaneous and thus requires an external heat supply.
