Abstract
This work describes the synthesis and photochromic properties of poly[N,N-[(3-dimethylamino)propyl]methacrylamide] bearing spiroxazines. Spiroxazine group showed reversible isomerization in this polymer upon photoirradiation. Solution viscosity of the polymer was reduced during irradiation and returns to the initial value after removing the light in DMSO. The ionic conductivity in polymer solution gradually increased upon UV irradiation and subsequently decreased in the dark.
