Icps 8100 spectrometer

All chemicals were obtained
commercially and were used without further purification. Na₉[A-α-PW₉O₃₄]·6H₂O was
prepared according to a previously reported method and was identified
by infrared (IR) spectroscopy according to the KBr disk method (Jasco
FT/IR-410 spectrometer).²⁰ Elemental analyses
(C, H, and N) were performed on Yanaco CHN Corder MT-5 and Vario EL
III elemental analyzers. The contents of Ln (i.e., Pr, Eu, Er, Y, and Ce), P, W, and Na were determined by inductively
coupled plasma atomic emission spectroscopy (ICP-AES) on an ICPS-8100
spectrometer (Shimadzu) and a Spectro ICP Ciros CCD spectrometer.
Thermogravimetric and differential thermal analyses (TG-DTA) were
conducted using an ULVAC MTS9000 + TGD9600 system.

GC analysis was performed with a flame ionisation detector using a 0.22 mm × 25 m capillary column (BP-5). The ¹H and ¹³C NMR spectra were recorded at 400 and 100 MHz, respectively. The ¹H and ¹³C NMR chemical shifts are reported in ppm with respect to the residual chloroform (¹H 7.26 ppm, ¹³C 77 ppm). The products were characterised by ¹H NMR, ¹³C NMR, and GC-MS. The TEM and STEM images were obtained with a JEOL JEM-ARM200F instrument at an accelerating voltage of 200 kV. Size distributions of nanoparticles were measured by counting 100 nanoparticles. ICP-AES was performed with a Shimadzu ICPS-8100 spectrometer. XPS analysis was performed with a ULVAC-PHI PHI5000 VersaProbe with Al Kα radiation. The measured spectra were calibrated by the C 1 s electron peak (284.5 eV). TG analysis was performed with a Thermo Plus EVO device (Rigaku, Japan) at a heating rate of 10 °C min⁻¹ under nitrogen flow.
All of the synthesised compounds (3a,^{23a (link)}3b,^23a 3c,^23a 3d,^23b 3e,^23a 3f,^23b 3g,^23e 3h,^23c 3i,^23d 5a,^{24a (link)}5b,^24c 5c,^24c 5d, 5e,^24b 5f,^24d and 5g^24b ) are known compounds and have been previously reported.
All of the starting materials were commercially available and used without further purification. The DMF-protected Pd NCs were prepared according to a previously reported method.^15a
