To obtain the liquid states, samples (~ 10 mg) were placed into a 70 μL Alumina crucible and heated above their respective melting offsets at a heating rate of 10 °C min -1 in SDT TA Q600 under Argon atmosphere. Differential Scanning Calorimetry (DSC) measurements were conducted using a TA Q2000 instrument. To obtain the glass transitions, the samples were reheated after cooling to low temperatures.
