The search for materials with non-linear optical (NLO) properties has been the subject of intense research, due to their application in a wide range of technologies, such as optical computing and optical communication. Although several inorganic substances are known to exhibit NLO properties, macroscopic assemblies of organic molecules show great promise as new materials for building NLO devices, due to their fast response times. With this purpose in mind, we designed a new class of molecules, using as central acceptor units, cyanosubstituted and fluoro-substituted ciclo-hexadienes, which exhibit considerably large electron-affinities. The candidate molecules were designed using four different central acceptor unit.
