Paper Abstract

The effects of a complex hybrid conjugation path in linear molecules as an strategy to optimize the intrinsic first hyperpolarizability is investigated. A series of 7 novel chromophores with different hybrid conjugation paths were synthesized and characterized. Hyper-Rayleigh scattering experiments confirm that complex hybrid conjugation paths, including benzene, thiophene and/or thiazole rings in combination with azo- and/or ethenyl-linkages, between a dihydroxyethylamino donor group and different acceptor groups, results in an enhanced intrinsic hyperpolarizability that exceed the apparent limit for two of the chromophores.
