Abstract
The photorefractive properties of polymer composites based on poly(N-vinyl carbazole), doped with the sensitizer C60, the plasticizer butyl benzyl phthalate, and two series of styrene-based chromophores are presented. These materials exhibit very fast response times (beam-coupling growth times τg as small as 60 ms at 50 V/μm applied field and 200 mW/cm2 intensity and τg as small as 5 ms at 100 V/μm and 1 W/cm2) of great interest for video-rate optical processing applications. The photorefractive properties are discussed in terms of the structure and oxidation potential of the chromophore.
