Tgdsc sta 449c instrument

The samples of LLM-116 and LLM-226 were supplied by Xi’an Modern Chemistry Research Institute. The compounds were synthesized through reported procedures [17 (link),35 ] (Scheme 1) All the samples were characterized by ¹H NMR, ¹³C NMR, FTIR and elemental analysis.
The thermal analysis experiments were performed with a model TGDSC STA 449C instrument (NETZSCH, Germany). Operation conditions: sample mass, 0.6 mg; atmosphere, dynamic nitrogen; aluminum cell. The IR spectra were recorded on a Nicolet 60SX FTIR spectrometer employing an HgCdTe detector.

The thermal analysis includes DSC, DSC-TG, in situ FTIR, and DSC-TG-FTIR-MS quadruple technology experiments. Thermal analysis experiments were carried out with model TG-DSC STA 449C instrument (NETZSCH, Germany) and DSC Q200 instrument (TA, America). Operation conditions: sample mass, 0.5 mg; atmosphere, dynamic nitrogen; aluminum cell. IR spectra were recorded on a Nicolet 60SX FTIR spectrometer with HgCdTe detector. In situ FTIR spectroscopy studies were carried out with Nicolet 60 SXR FTIR spectrometer. Operation conditions: sample mass, 0.5 mg; heating rate, 10 °C/min; resolution, 4 cm⁻¹; spectral acquisition rate, 17.8 file/min, 16 scans/file; temperature range, 20~450 °C.
