The linear and nonlinear optical (NLO) properties of these compounds have been determined and compared with the results of computational calculations. The position of the thiophene ring proved essential to optimize the figure of merit μβ, with the best results obtained when the heterocyclic system was closer to the donor moiety. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.564 2012 CHEMISTRY, ORGANIC 10 / 57 = 0.175 2012 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Garí­n, Javier Orduna, Jesús (orcid)0000-0003-3514-2570 Andreu, Raquel.
