1 DSC conditions: 20 °C/min, He; 2 Measured during the second heating cycle; 3 TGA conditions: 20 °C/min to 600 °C, N2; 4 TGA conditions: 10 °C/min from 40 °C to 900 °C, N2, Pt pan (100 μL). Every sample was dried in the furnace at 60 °C for 10 min under an N2 atmosphere prior to measurement; 5 Referred to the first degradation event; 6 Referred to the second degradation event; 7 Referred to the third degradation event; 8 DSC conditions: The samples were heated to the maximal temperature (10 °C/min) to remove thermal history, then cooled to −90 °C (5 °C/min) and heated from −90 °C to the maximal temperature (10 °C/min) (the two heating ramps lead to the same results), dry N2 (30 cm3/min), 1.44–7.21 mg, aluminum pan with a pinhole on the cap, the maximal temperature was 180 °C for 83a,b, 84a,b, 300 °C for 83c and 84c, 250 °C for 83d and 210 °C for 84d.
