The representative complexes 2 and 8 (1 mM in DMF-d7, MeOD-d4, 10% DMF-d7/D2O and 10% MeOD-d4/D2O) or their mixtures with 2 molar equivalents of GSH in 10% MeOD-d4/D2O were studied by 1H NMR (acquired at 298 K on JEOL JNM-ECA 600II) right after the preparation of the studied solutions (0 h) and after 1 h, 24 h and 48 h of standing at ambient temperature. Analogical experiments were performed in non-deuterated solvents (10% DMF-d7/D2O, 10% MeOH/H2O) and analysed by ESI+ mass spectrometry (LCQ Fleet Ion Trap mass spectrometer).

The glass structures were evaluated using laser Raman spectroscopy (NRS‐5100; 532.02 nm, 5.7 mW, 220–1,300 cm−1; JASCO) and solid‐state magic angle‐spinning nuclear magnetic resonance (MAS‐NMR) spectroscopy. 31P MAS‐NMR spectra were evaluated with a pulse width of 3.0 μs, recycle delay of 60 s, and cumulative number of 256 (3.2 mm rotor spinning at 15 kHz, resonance frequency 242.85 MHz; VNS600, Agilent Technologies). Ammonium dihydrogen phosphate (NH4H2PO4, 1.0 ppm) was used as a reference to analyze the chemical shifts. 29Si MAS‐NMR spectra were evaluated with a pulse width of 7.5 μs, recycle delay of 240 s, and a cumulative number of 700 (8.0 mm rotor spinning at 5 kHz, resonance frequency 119.24 MHz; JNM‐ECA600II, JEOL). 3‐(Trimethylsilyl)‐1‐propanesulfonic acid sodium salt (0.0 ppm) was used as a reference to analyze the chemical shifts.

1H NMR spectra of i-DWNT complexes were recorded on a JEOL RESONANCE JNM-ECA 600 II equipped with an UltraCOOL probe. The spectrum of an equimolar mixture of (P)-(20,4), (M)-(20,4), (P)-(9,6) and (M)-(9,6) was recorded at a total concentration of 1 mM in CD2Cl2 (Fig. 4a). Spectra of (P)-(20,4)⊃(M)-(9,6) and (P)-(20,4)⊃(P)-(9,6) were also recorded at a total concentration of 1 mM in CD2Cl2 (Fig. 4b).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
