✦ Synopsis

The photochromic behaviour of 3,3-bis[4-(N, N-dimethylamino)phenyl]-3/%naphtho[2,I-b]pyran (2) and 2,2-bis[4-(N, N-dimethylamino)phenyl]-2H-l -benzopyran (3) has been studied by flash photolysis and compared to 3,3-diphenyl-3/-/-naphtho[2,1-b]pyran (1 ) in order to delineate effects due to the N,N-dimethylaminogroups. 01997Elsevier Science Ltd.

The photochromic parameters of a set of 26 thiophene-substituted [3H]-naphtho[2,1-b]pyrans were studied by flash photolysis. The experimental results obtained along with molecular modelling approaches (molecular mechanics and quantum calculations) allowed us to propose structure-property relationshi
