The photochromic behaviour of 3,3-bis[4-(N,N-dimethylamino)phenyl]-3H-naphtho[2,1 -b]pyran (2) and 2,2-bis[4-(N,N-dimethylamino)phenyl]-2H-1 -benzopyran (3) has been studied by flash photolysis and compared to 3,3-diphenyl-3H-naphtho[2,1 -b]pyran (i) in order to delineate effects due to the N,N-dimethylamino groups.
