Y. Sugiyama et al., 2ND-ORDER OPTICAL NONLINEARITIES OF BETA-SULFONYLSTYRENE DERIVATIVES, Bulletin of the Chemical Society of Japan, 67(12), 1994, pp. 3346-3348
The second-order optical nonlinearities and transparencies of eight su
bstituted styrenes containing at least one sulfonyl group at the beta-
position, as the electron-withdrawing group, were examined. Oxidation
at a sulfur atom (SMe-->SOMe-->SO(2)Me) brings about increases in the
beta and lambda(max) values.
