R. Matsushima et H. Sakaguchi, COMPARISON OF THE PHOTOCHROMIC PROPERTIES OF FULGIDES AND FULGIMIDES, Journal of photochemistry and photobiology. A, Chemistry, 108(2-3), 1997, pp. 239-245
Photochromic properties of some arylfulgimides such as furyl-, thienyl
-, and thiazolylfulgimides were compared with corresponding fulgides i
n detail. Photochemical reversibility and thermal stability as well as
the photochromic response of fulgimides were substantially comparable
with those of the fulgides, both in solution and in solid polymer fil
m. Fulgimides revealed high resistance to solvolytic degradation in hy
droxylic media while corresponding fulgides underwent rapid degradatio
ns. Thus, N-(4-carboxyphenyl)fulgimide, being soluble in aqueous media
, revealed moderate photochromic performance in aqueous ethanol soluti
on without extensive solvolytic degradation, as well as in ionic polym
er film of allylamine hydrochloride. (C) 1997 Elsevier Science S.A.
