*2.8. Di*ff*erential Scanning Calorimetry (DSC)*

Thermal analyses of these samples were performed on a DSC (Q200 V24.10 Build 122) instrument (New Castle, DE, USA): 2–3 mg of the crystals was placed in standard aluminium pans and scanned at 20 ◦C/min in the range 25–280 ◦C under a nitrogen gas flow of 50 mL/min. Data were analysed using the Universal Analysis 2000 software (New Castle, DE, USA).
