On August 31, 1993, Kamogawa, Hiroyoshi; Nanasawa, Masato published an article.Related Products of 52243-87-5 The title of the article was Effect of temperature on the color developed by near ultraviolet light for 4,4′-bipyridinium salts (viologens) embedded in poly(1-vinyl-2-pyrrolidone) matrix. And the article contained the following:
Thermal stability of the colors developed by UV light for 4,4′-bipyridinium salts (viologens) embedded in the glass-sandwiched poly(1-vinyl-2-pyrrolidone) is dominated by the kind of counter anion. Temperature increase resulted in either no or slight changes of the colors developed for the major viologens, whereas it resulted in bleaching for some viologen sulfonates. The experimental process involved the reaction of 1,1′-Dipropyl-[4,4′-bipyridine]-1,1′-diium bromide(cas: 52243-87-5).Related Products of 52243-87-5
