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. 000165339 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000165339 590__ $$a4.564$$b2012 000165339 591__ $$aCHEMISTRY, ORGANIC$$b10 / 57 = 0.175$$c2012$$dQ1$$eT1 000165339 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000165339 700__ $$aGarín, Javier 000165339 700__ $$0(orcid)0000-0003-3514-2570$$aOrduna, Jesús 000165339 700__ $$0(orcid)0000-0002-3206-9868$$aAndreu, Raquel.$$uUniversidad de Zaragoza 000165339 700__ $$0(orcid)0000-0001-7193-1732$$aBlesa, María Jesús$$uUniversidad de Zaragoza 000165339 700__ $$0(orcid)0000-0001-9814-0834$$aVillacampa, Belén$$uUniversidad de Zaragoza 000165339 700__ $$aAlicante, Raquel 000165339 700__ $$0(orcid)0000-0001-9747-1789$$aFranco,Santiago$$uUniversidad de Zaragoza 000165339 7102_ $$12013$$2765$$aUniversidad de Zaragoza$$bDpto.
