First hyperpolarizabilities of stilbenes derivatives
Stilbene and heteroaromatic stilbene derivatives have been synthesized and their beta values were determined. The result of HRS measurements indicates that the beta (0) values are larger for the heteroaromatic stilbenes than the stilbenes. For stilbene derivatives, the beta (0) increased as the acceptor strength was increased.
