After 1 h, the precipitated polymeric mate- rials were collected by centrifugation and washed with water repeatedly, followed by drying in vacuo to give the polymer. Polym. J., Vol. 36, No. 12, 2004 1H NMR (DMSO-d6): 3.3–3.6 (m, CH2CH2O), 6.6–7.4 (br, Ar), 9.2–9.6 (br...
6. The crystalline solvate of claim 1 or 4, wherein the crystalline solvate is further characterized by a powder X-ray diffraction pattern having one additional diffraction peak at a 2θ(°) value of 22.44±0.20. 7. The crystalline solvate of claim 6, wherein the crystalline solvate is fur...
The DS is calculated from the 1H-NMR spectrum recorded in DMSO-d6 containing a small quantity of water represented in FIG. 8. The following broad signals with chemical shifts of the maxima of the signals are identified:1. S1 δ 8.0-8.1 ppm CH (TIB-Phenyl, para position) 2. S2 δ ...
In ethanol the dye absorption has a peak at 550 nm with a vibrational shoulder at 516 nm (548 nm and 514 nm, respectively, in methanol); in water the absorption of the dye is about 6 nm shifted to the blue. Since the formation of the first singlet excited state is due to π- π...
Interestingly, no induced CD at the Molecules 2017, 22, 1084 6 of 17 The negative CD peak (at 245 nm) displays little decrease in intensity and the positive band (at 277 nm) remain nearly unperturbed with increasing 2-Mn and 2-Fe concentration, which means the bMinoldeciunlegs 2o0f172...
The analogous fragmentation in the ESI mass spectrometry was observed for the relevant CuI complexes with the octahedral copper-halide core [2,8]. In the mass spectrum of the separated colloidal phase this fragmentation was not observed, whereas the major peak in the spectra (m/z 1794) ...
1H NMR and 13C NMR spectra were measured using a BrukerAV-400 spectrometer (Bruker, Karlsruhe, Germany) with chemical shifts reported in ppm, (in CDCl3 or Dimethyl sulfoxide-d6 (DMSO-d6); Tetramethylsilane (TMS) as an internal standard). Electrospray ionization mass spectra (ESI-Mass) ...
The obtained compounds were dissolved in 0.5 mL of DMSO-d6 and the solution was filled into a NMR tube. NMR analysis was carried out using a Bruker 300 MHz spectrometer operating at 300 (1H) or 75 MHz (13C), respectively. Chemical shifts were reported in ppm on δ scale, and the ...
