- Аннотация: Two pH-sensitive spin probes 4-(methylamino)-2-ethyl-5,5-dimethyl-4-pyridine-2-yl-2,5-dihydro-1H-imidazol-1-oxyl (DPI, also known as MEP) and 2,2,3,5,5-pentamethyl-2,5-dihydro-1H-imidazol-1-oxyl (MTI) were used to measure pH of water intercalated in Brodie graphite oxide. The pH value was found to be 2.25 ± 0.05 immediately after adding water to graphite oxide and decreased to 1.75 ± 0.05 during ca. 30 h.
