    Summary form only given. Since the first observation of photorefractivity in a polymer composite, applications to information-processing and dynamic holography have spurred rapid development. A critical step was the realization that index-modulation is enhanced by reorientation of birefringent chromophores in composites with low glass-transition temperatures, Tg. Now attention has turned to understanding and improving response-times. A composite with a 4-ms component has been reported recently, with persuasive evidence that photoconductivity limits speed. We report an even faster 1.8-ms component in a very different composite a fluorinated cyanotolane chromophore
