Synthesis and properties of polyvinylpyrrolidone films containing the photomagnetic chromium (tris)oxalate complex
Russian Chemical Bulletin(2013)
摘要
Uniform composites of polyvinylpyrrolidone with the paramagnetic chromium (tris)oxalate complex (C 23 H 23 N 2 O + ) 3 Cr(C 2 O 4 ) 3 ·11.56 H 2 O and cation of quinoline spiropyran of the indo-line series were obtained for the first time. Their photochemical properties and static and superhigh-frequency dynamic magnetic characteristics were studied. The change in the ESR spectra under UV irradiation in films of polyvinylpyrrolidone containing photochromic paramagnetic was observed.
