The volatilization curve was collected using a TA Instruments thermogravimetric analysis Q500 tool. The ramp experiment of 1 was undertaken inside a nitrogen glovebox in a tared aluminum pan loaded with 18 mg of 1. The furnace was heated at a rate of 10 °C/min to 400 °C with a maintained nitrogen flow rate of 60 sccm. The differential scanning calorimetry (DSC) measurement for 1 was performed on a TA Instruments DSC Q10 tool. The sample was prepared in a sealed aluminum pans in a N2 filled glovebox and weighed approximately 0.2 mg.
