A new bifunctional chromophore working at short wavelength in photorefractive polymer composite

We has successfully synthesized a new bifunctional electro-optic chromophore, /spl beta/,/spl beta/-diacetyl-4-methoxylstyrene (DAMST) and fabricated the photorefractive polymer film doped with this chromophore. This composite was proved to possess good photorefractive properties at short wavelengths. Research at the 440 nm wavelength is in progress.
