Solution ¹H NMR spectra were recorded at 500 or 600 MHz using a Bruker Avance 500 or 600 NMR spectrometer. Powder X-ray diffraction (PXRD) data were collected on a Rigaku Ultimate-IV X-ray diffractometer operating at 40 kV/30 mA using the Mo Kα line (λ = 1.5418 Å). Data were measured over the range of 5 − 40° in 5°/min steps over 7 min. Thermogravimetric analysis (TGA) was carried out using a Q5000IR analyzer (TA Instruments) with an automated vertical overhead thermobalance. The samples were heated at 10 °C/min using N₂ as the protective gas. Single crystal X-ray diffraction data were collected on a Bruker D8 VENTURE CMOS X-ray diffractometer with graphite monochromated Mo Kα radiation (λ = 0.71073 Å). Diffuse reflectance spectra were recorded with a SHIMADZU UV-2550 spectrometer. UV-vis absorption spectra were recorded using a PerkinElmer Lambda 35 UV-vis spectrophotometer. Differential Scanning Calorimetric study (DSC) was carried out using a DSC Q100 analyzer (TA Instruments). The samples were heated at 10 °C/min using N₂ as the protective gas. The FT-IR spectra were measured on a Perkin Elmer 480 FT-IR spectrophotometer (KBr pellet). The Raman spectra were measured on a Horiba scientific-LabRAM HR evolution.

The contact was analyzed using Raman spectroscopy (HORIBA Scientific LabRAM HR Evolution, HORIBA Jobin Yvon, Paris, France) with a Raman shift of 800–2000 cm⁻¹.
