Vega3 sb microscope

All the reagents and solvents used in the synthesis experiments were of analytical grade and were used without further purification. A Nicolet^TM iS10 FT-IR spectrometer (Thermo Fisher Scientific, Waltham, MA, USA) with a Monolithic Diamond ATR accessory and absorption in cm⁻¹ was used for recording IR spectra. Nuclear magnetic resonance (¹H NMR and ¹³C NMR) spectra were recorded on a BRUKER Avance 400 instrument (400.131 MHz for ¹H and 100.263 MHz for ¹³C) dimethyl sulfoxide-d₆; the chemical shifts are given in δ units (ppm). RP-HPLC analyses were performed using an Agilent 1200 liquid chromatograph (Agilent, Omaha, NE, USA). The elemental analysis for carbon and hydrogen was carried out using a Flash 2000 elemental analyzer (Thermo Fisher Scientific, Waltham, MA, USA). Scanning electron microscopy (SEM) analysis was done on a VEGA3 SB microscope (TESCAN, Brno-Kohoutovice, Czech Republic).

The reagents and solvents were obtained from Merck (Darmstadt, Germany). A Nicolet^TM iS10 FT-IR spectrometer (Thermo Fisher Scientific, Waltham, MA, USA) with a Monolithic Diamond ATR accessory and absorption in cm⁻¹ was used for recording the IR spectra. Raman spectra were recorded on a DXR Raman Microscope (Thermo Fisher Scientific, Waltham, MA, USA) with Raman shift in cm⁻¹. The elemental analysis for carbon and hydrogen was carried out using a Flash 2000 elemental analyzer (Thermo Fisher Scientific, Waltham, MA, USA). Scanning electron microscopy (SEM) analysis was done on a VEGA3 SB microscope (TESCAN, Brno-Kohoutovice, Czech Republic). The samples were coated with gold in a 99.99% plasma state of purity in a metallizer. The thermogravimetric analysis was carried out with a thermogravimetric analyzer with large furnace (LF) TGA/DSC 3+ (Mettler Toledo, Columbus, OH, USA). 10 mg of each compound was heated from 30 °C to 1000 °C (heating rate of 5 °C/min). Nuclear magnetic resonance (¹H NMR and ¹³C NMR) spectra were recorded on a BRUKER Avance 400 instrument (400.131 MHz for ¹H and 100.263 MHz for ¹³C), and chemical shifts are given in δ units (ppm). HILIC-HPLC analyses were performed using an Agilent 1200 liquid chromatograph (Agilent, Omaha, NE, USA).

UV-Vis spectra were recorded on an EMC-11-UV spectrophotometer within a range of 200–800 nm. RP–HPLC analyses were performed on an Agilent 1200 liquid chromatograph (Agilent, Omaha, NE, USA) using a Chomolith^® C18 column (Merck, 50 mm).
