however, they are only dissolving in water. We took the NMR using deuterated H20, and the water peak at around 4.7 ppm drowns out the rest of the NMR. We have tried dissolving the compounds in typical organic solvents. However, all the solvents and even DMSO is not dissolving the compound...
H NMR spectra were recorded on a Bruker Avance 300 MHz NMR spectrometer using DMSO-d 6 or D 2 O (Cambridge Isotope Laboratories) with the solvent peak as a reference. Monomer conversion was determined by reverse-phase HPLC analysis on a ...

Further details of the synthesis of 242 and YI-1 were described in the Additional file 1, including NMR and mass spectra results (Additional file 1: Scheme S1 and Figs. S2–S17). The loading efficiencies of PSMA NPs for 242 and YI-1 were both larger than 85% (Additional file 1: Fig...

The 1H NMR spectra of A-Cur (Fig. 2b) exhibited a peak ranging from δ 2.4–2.52 because of the protons of CH2 of ethylenediamine, However, no peak was observed for the amine protons, which is most likely due to proton exchange [39,60,67]. In the 1H NMR spectra of Cur-Cum conjuga...
(Pd/NPW)/TiO2excited by a 320 nm laser are shown in Supplementary Fig.13. Clearly, all three samples exhibit one broad peak from 350 nm to 600 nm, representing the radiative emission of charge carrier recombination37. Compared with pristine TiO2and Pd/TiO2, the significantly quenched ...
NMR (DMSO-d6-D2O, 100°C) δ ppm; 7.50-6.70 (10H, m), 5.50-5.40 (1H, m), 5.00-2.50 (2H, m), 2.37 (6H, s), 2.40-1.50 (4H, m) Example 4 A 3.0 g quantity of compound (1a-2) was dissolved in 100 ml of methylene chloride, and a solution of 10 ml of trifluoroacetic ac...
1H and 13C NMR spectra were recorded on a Bruker AV 400 Ultrashield spectrometer using dimethylsulfoxide-d6 (DMSO-d6) or CDCl3 as solvent. Chemical shifts were reported Synthesis All the compounds were prepared according to the synthetic routes showed in Scheme 1. The characterization data ...
We used Raman spectroscopy to investigate the resonant structural changes in PEDOT with different Iso-GMA concentrations in the PEDOT:PSS/DMSO films (Fig. 2c). The characteristic Raman peak for the PEDOT without Iso-GMA was located at 1430 cm−1. This was assigned to the C α = ...
