It is shown experimentally that the complete replacement of benzene rings with thiophene rings in a donor-acceptor substituted stilbene significantly enhances its second-order nonlinear optical hyperpolarizability (β); results obtained with a series of thiophene-substituted donor-acceptor compounds with different conjugation lengths reveal a power law dependence of βμ on the molecular conjugation length.
