在诸如光学数据存储的应用中，非晶有机光折变（PR）材料的性能通常受到活性分子（发色团）的浓度的限制，所述活性分子（发色团）可以并入到主体中而不形成具有差的光学质量的结晶材料。在先前描述的聚合物PR系统中，性能受到将大部分材料用于惰性聚合物和增塑组分以确保组成稳定性的必要性的限制。介绍了一类由多功能玻璃态有机发色团组成的新型有机光致变色材料，该材料具有长期稳定性和显著改善的光致变色性能。
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.
