Description
Summary:We have developed an experimental setup for the measurement of the polarizability anisotropy of push–pull molecules in solution. We have used this technique to investigate prototype push–pull molecules that have been incorporated as doping chromophores in low glass transition temperature photorefractive polymers. Results obtained evidence for these compounds that the refractive index modulation is dominated by the orientational birefringence contribution while the electro-optic contribution remains small.
