Kato, Chuzo; Kuroda, Kazuyuki; Sugawara, Yoshiyuki; Miyata, Hirokatsu published an article in 1987, the title of the article was Synthesis of montmorillonite-viologen intercalation compounds and photochromism.HPLC of Formula: 52243-87-5 And the article contains the following content:
Photochromic behavior of viologen I (R = Pr, n-heptyl, benzyl, phenethyl) intercalated into the layers of montmorillonite with poly(vinylpyrrolidone) (PVP) and poly(vinyl alc.) (PVA) was studied. When irradiated with a Hg lamp, the intercalation compounds turned blue to give radical cations, whereupon PVP and PVA served as electron donors for reduction of I. The radical cations generated in montmorillonite were more stable than those in the PVP matrix. The experimental process involved the reaction of 1,1′-Dipropyl-[4,4′-bipyridine]-1,1′-diium bromide(cas: 52243-87-5).HPLC of Formula: 52243-87-5
