Vn. Nemykin et al., SYNTHESIS AND STUDY OF CHEMIOCHROMIC PROPERTIES OF HIGHLY SOLUBLE DYSPROSIUM OCTA-TERT-BUTYLDINAPHTHALOCYANINATE, Russian chemical bulletin, 44(10), 1995, pp. 1883-1885
Chemiochromic properties of dysprosium octa-tert-butyldinaphthalocyani
nate were studied by electron spectroscopy. An initial blue form is ch
emically oxidized and reduced in an inert atmosphere to form stable gr
een and pale green forms that are reversibly transformed into one anot
her.
