V 670 uv vis nir spectrometer

The optical response of the prepared nanoparticles was characterized by means of UV–Vis absorption spectroscopy. Absorption spectra were recorded using a Jasco V-670 UV–Vis–NIR spectrometer (Jasco, Easton, MD, USA) with a slit width of 2 and 1 nm spectral resolution. Particle size distribution and zeta potential were measured using a Zetasizer NanoZS90 instrument (Malvern Instruments, Malvern, UK). Analysis was performed at a scattering angle of 90° at 25°C (Figure S1).

X-ray fluorescence spectrometry was performed on a SHIMADZU EDX-7000 spectrometer. IR spectra were recorded on a JASCO FT/IR-4700 infrared spectrophotometer using the ATR method at room temperature. Solid-state diffuse reflection spectra were measured on a JASCO V-670 UV/Vis/NIR spectrometer and solid-state CD spectra were recorded on a JASCO J-820 spectrometer at room temperature. Elemental analyses (C, H, N) were performed at Osaka University using a Yanaco CHN Corder MT-6. The powder X-ray diffractions were recorded at a controlled temperature in transmission mode [synchrotron radiation λ = 1.0 Å; 2θ range = 2–78°; step width = 0.01°; data collection time = 1 min] on a diffractometer equipped with a MYTHEN microstrip X-ray detector (Dectris Ltd) at the SPring-8 BL02B2 beamline. The crystals were loaded into a glass capillary tube (diameter = 0.3 mm), which was rotated during the measurements.

The IR spectra were collected on a JASCO FT/IR-4100 infrared spectrophotometer by using the KBr method at room temperature. The circular dichroism spectra were recorded on a JASCO J-820 spectrometer at room temperature. The diffuse reflection spectra were measured on a JASCO V-670 UV/Vis/NIR spectrometer. X-ray fluorescence spectrometry was performed on a Shimadzu Model EDX-7000 spectrometer. Elemental analyses (C, H, N) were performed at Osaka University using a Yanaco CHN Corder MT-6. The ¹H NMR spectra were recorded on a JEOL ECS400 (400 MHz) spectrometer in D₂O. Sodium 4,4′-dimethyl-4-silapentane-1-sulfonate (DSS) was used as the internal standard. High-quality powder X-ray diffraction (PXRD) patterns were recorded at room temperature in transmission mode [synchrotron radiation λ = 1.0 Å; 2θ range = 2°–78°; step width = 0.01°; data collection time 1 min] on a diffractometer equipped with a MYTHEN microstrip X-ray detector (Dectris Ltd) at the SPring-8 BL02B2 beamline. The crystals in the mother liquor were loaded into a glass capillary tube (diameter = 0.3 mm), which was rotated during the measurements. The powder simulation patterns were generated from the SCXR structures using Mercury 3.10.
