Nicolet is 10 ft ir instrument

The Fourier-transform infrared spectroscopy (FT-IR) analysis of FCP (1 mg) mixed with potassium bromide powder at a range of 4000–400 cm⁻¹ was performed on an FT-IR spectrophotometer Nicolet iS 10 FT-IR instrument (Thermo Fisher Scientific, Waltham, MA, USA) [28 (link)].

¹H, ¹³C, and ³¹P nuclear magnetic resonance (NMR) spectra were recorded on a JEOL ECP-300 instrument (300 MHz, 75 MHz, and 121 MHz for ¹H, ¹³C, and ³¹P NMR, respectively). The chemical shift values were expressed relative to tetramethylsilane (TMS) as an internal standard for ¹H and ¹³C NMR spectra and 85% H₃PO₄ as an external standard for ³¹P NMR spectra. Fourier transform infrared (FT-IR) spectra were measured on a Thermo Scientific Nicolet iS10 FT-IR instrument. Size exclusion chromatography (SEC) measurements were performed on a Shimadzu LC-10AS liquid chromatograph equipped with a Shimadzu RID-10A refractive index detector and Tosoh TSK-gel GMHHR-M tandem columns using chloroform (CHCl₃) as an eluent (1.0 mL/min) at 35°C. UV–vis absorption spectra were recorded in CHCl₃ on a Shimadzu UV-3100PC spectrometer. Cyclic voltammetric (CV) analyses were carried out on a Versa STAT3 (Princeton Applied Research) potentiostat at a scan rate of 100 mV/s. All the measurements were performed in dry acetonitrile containing 0.10 M tetra-n-butylammonium hexafluorophosphate at ambient temperature using a three-electrode system, with each solution being purged with N₂ prior to measurement. The working electrode was a platinum (Pt) disk (ϕ = 1.6 mm, BAS, Japan), the counter electrode was a Pt wire, and the reference electrode was a silver (Ag) wire.
