We have closely investigated these novel types of push-pull chromophores with respect to their NLO and thermal properties . Hyper Rayleigh scattering measurements at a fundamental of 1,500 nm have revealed that b-values are surprisingly large for such short dipoles (3a: b0333 ¼ 31 Â 10À30 esu; 3b: b0333 ¼ 29 Â 10À30 esu). With respect to the relatively low molecular mass, these chromophores display a rather favorable molecular figures of merit, b0m/Mw, where Mw is the molar mass. , glass transitions, a favorable property for composites in photo refractive materials.
