The performance of amorphous organic photorefractive (PR)
materials in applications such as optical data storage is generally limited by the concentration of active molecules (chromophores) that
can be incorporated into the host without forming a crystalline material with poor optical quality. In polymeric PR systems described previously, performance has been limited by the necessity of devoting a
large fraction of the material to inert polymer and plasticizing components in order to ensure compositional stability. A new class of
organic PR materials composed of multifunctional glass-forming organic
chromophores is described that have long-term stability and greatly
improved PR properties.
